After a busy week working across London, #teamgo have finished the third 100 Women Challenge tackling sexual harassment.

We will keep you updated on what happens on their #UnmuteTheCommute campaign aimed at destigmatising reporting of sexual harassment on London's public transport.

Thank you for following our progress - you can still tweet us using #100Women

The BBC 100 Women team now need to pack their suitcases to head to Rio de Janeiro to look at sexism in sport for our final challenge!

You can follow progress on the BBC 100 Women website, and on Twitter, external,Facebook, external and Instagram, external.

The season will also be featured on BBC News, BBC World television and World Service Radio.

Two weeks ago BBC 100 Women contributor Roya Ramezani created an installation called "me too" just hours before the New York Times story about Hollywood producer Harvey Weinstein broke.

Since it happened Twitter users have been sharing #metoo stories about their experiences of harassment and sexual abuse.

Anne-Marie Imafidon, one of #teamgo who made the badge solution, has expanded on how it works.

"It allows you to alert bystanders if you feel something is about to happen or you are being sexually harassed or attacked."

And then others who are wearing the badge will also notice theirs lighting up.

"It's making the unseen seen," Anne-Marie says. "It takes the onus off the victim - it puts it on other people."

Sian Lewis, who herself has experienced harassment on the bus, said she thought it was a good idea.

"It's such a quick in-the-moment solution... if you can be active in that moment, and know people around you are going to support you, then I think that's huge."

Ellie Cosgrave, another #teamgo member and research associate on the 'livable cities' project at University College London, emphasised that public transport harassment is "a global problem... this is something that we all have to tackle as a global community".

BBC Breakfast had a sneek peek earlier and saw some of the solutions #teamgo have been working on all week.

Have a watch!

The additional 10 names of women who have been involved in our public safety challenge have been announced. Take a look, external.

The team's 2nd solution focuses on how the public could help women who are experiencing harassment.

The 'unmute the commute' badge......

#teamgo have designed special "un-mute" badges, similar to existing Baby on Board badges for pregnant women to wear on public transport. These can be activated to light up and vibrate in order to alert people nearby that someone is standing too close to a wearer and that an incident is taking place.

People taking part in #teamgo's reveal show listen to real testimony from victims of harassment and have a visual reminder of the potential hazards on board.

Laura Jordan Bambach, one of #teamgo, who came up with the bus slogan, says there's an issue of people being "passive bystanders... not speaking up, not wanting to offend anyone."

"This campaign is all about getting those passive bystanders to step in and also to be trained to know what to do to intervene," she says.

Laura points out that TFL [Transport for London] haven't ever had any messages on tubes and buses around London about sexual harassment.

Hanne Bingle, another of the team who spent years driving tube trains, says she's very impressed with what they came up with.

"We have a collective responsibility to make sure everybody in our society is safe," she says.

Michael Conway from A Call to Men UK, who are a group committed to ending Male Violence Against Women and Girls, watched a virtual reality film on sexual harassment as part of our BBC 100 Women campaign.

Their VR film re-creates instances of sexism and street harassment and aims to give watchers a visceral experience of what it’s really like to be attacked in the street or on public transport.

People have been sharing their sexual harassment experiences on public transport using our #UnmuteTheCommute hashtag on twitter.

Our #teamgo group has been working on ways to encourage women to report harassment

They have come up with an '#UnmuteTheCommute' slogan to let women know they should feel able to express distress, and to remove any stigma surrounding reporting incidents.

And there are several installations on-board their specially-adapted '#UnmuteTheCommute' bus.

In the stairwell there are foam hands dangling down to recreate the invasion of privacy women may feel on public transport.

And upstairs there is an audio installation made up of anonymous testimonies shared by members of the public with Hollaback; a network of activists dedicated to ending street harassment in London.

During our Challenge week, Outside Source's presenter went along with #teamgo and campaigner Sian to a special self defence class to learn how to defend themselves if they felt threatened.

Sian said she believes it can be incredibly empowering for some women.

"But the onus shouldn't be on us to be strong and be able to protect ourselves," she said.

"These sorts of things shouldn't be happening in the first place. If you're having to defend yourself the problem has already happened."

One viewer, Elizabeth, saw our undercover video earlier and came down to our special #UnmuteTheCommute bus in Convent Garden.

"I saw the video of the police officer on the underground who catch harassers and then heard about the bus and came down," she said.

"The message on the bus really worked for me. I hope it works for others"

You, our audience, have been telling us the lengths you go to in order to avoid potential threats on public transport.

Dee Dee explains why she wanted to come down and see our bus for herself....

BBC 100 Women went undercover with British Transport Police officers who try to catch offenders on the tube.

Transport for London say 90% of sexual behaviour on the capital's transport network goes unreported.

100 Women has been focusing on harassment in public transport this week and one of the questions we have heard from women was : "Who do I report it to?"

To report in London, you can:

• Text the transport police on 61016 about the incident
• Call 101 or 0800 40 50 40
• Use the passenger alarm
• Approach a nearest staff member in the bus or tube
