Thanks for all your emails on the debate on women in leadership. Please keep them coming! 

Fatima Shamim sent an email to BBC100.Women@bbc.co.uk saying women and men are not that different.

A debate on leadership is under way at the Rape Crisis Cape Town Trust. “We have to act like men to be seen as competent, but then are called bossy when we do,” says one of those taking part.

A group of girls from BBC School Report are in the London studio watching the debate and some of the participants offered them some advice.

Natalie Campbell, founder of A Very Good Company, said: “Always be entrepreneurial; have a can do attitude – when someone says 'no', there’s always someone else that will say 'yes'.”

"Challenge," says Hanna McCloskey, the founder of Fearless Futures. "Do not accept the world as it looks today - inequality is not inevitable,"

This group is talking about women, image and marriage in India.

So far they have said: “Men pick women for marriage by making them parade and selecting them based on their own ideas of beauty."

They add: "The dowry is higher or lower depending on men's idea of beauty. They are bullied as 'buffalo' or 'bulldozer' by their husbands if they are fat or black.”

Ines Wichert, author of Where Have All the Senior Women Gone?, said at IBM they were trying a new type of mentoring.

She told the debate in London: “We have been doing reverse mentoring - younger women mentoring senior men.

The latest discussions getting under way in the next hour are being held by the Association of Women of Abkhazia and the American Women's Group in Paris.

The London debate is now discussing the barriers that might hold women back. Sally Boyle, HR director at Goldman Sachs, says: “One of the hardest things is returning from maternity leave. That’s all about the manager of the pregnant woman integrating them well, and understanding what their challenges are going to be.”

The Hong Kong Book Club is talking about the effect of educating girls separately from boys.

Here’s one view from this debate so far: “I think that masculinity and acting like a man is the norm. Participating out of that means you are ostracised.”

At the London debate, Lubna Qasim, a lawyer, banker & former UAE government official, said she had not had the best experience with female managers. 

She said: "The best bosses I had were male bosses and the female bosses taught me not what to do when I reach there.

Here are some messages from our latest 100 Women debate to kick off.

At the London debate, we're asking "Do women help other women to reach the top?"

Natalie Campbell, the founder of A Very Good Company, said she has been "very blessed".

Lindsay Orridge from the Motorsport Collective, external has been in touch:

Kelly Yang joined the debate in London via videophone from Hong Kong. She said attitudes towards women need to change.

The debate in London is asking how women can get ahead?

Sally Boyle, Partner & HR Director at Goldman Sachs, said: “I think that one of the problems is that women think doing a good job and keeping their head down will get them noticed and promoted…I don’t think women find it natural to promote themselves.”

Welcome to those taking part around the world this hour. In the UK, the Kings College London Feminist Society is holding an event, as is the Housewives in Nigeria group in Abuja. In Germany, the group Women in Europe for a Common Future (WECF) is leading a debate with other organisations internationally.
