Marian: How about spraying the Tower Moat with real poppy seeds before the ceramic poppies are removed. The disturbance to the ground when removing the ceramic poppies will help the real flowers to grow just as in the Flanders Fields. Hopefully this could give us a display for the next four years and more.

The Met Office have published an article online documenting the important role they played during World War One. It says:
By the end of the war forecasters and observers were to be found working in support of the army on every front. Met Office staff worked on the front line predicting changes in the wind that might indicate the risk of the enemy launching gas attacks. Both sides used gas as a weapon during the war and the forecasters also advised on when conditions were right for the allies to launch gas attacks. It was a highly dangerous role.
The role of the Met Office and the importance of weather information and advice to military operations were considered so critical by the end of the war that the Met Office became part of the Air Ministry which ran the Royal Air Force.

Armistice Day has been marked on 11 November every year since 1919 - a year after the Allied forces signed an agreement with the Germans that would end WW1.
After the Second World War, commemorations were adapted to honour the fallen of both conflicts, and Remembrance Sunday was established to replace Armistice Day.
From 1995, the British Legion campaigned successfully to restore the two-minute silence to 11 November as well as Remembrance Sunday.

Tom Piper, designer of the poppy installation at the Tower of London, told the BBC he thought the sale of the poppies had raised "at least £1m for each of the six charities".
"I'm very thrilled and honoured that it's had such an impact. I don't think we imagined that it could have [raised this amount] when we set out to do it," he said.

Incredibly moving that so many students, staff and tutors came to pay their respects. My great grandfather fought at Gallipoli and on the Western Front, and my great-great uncle was killed exactly a month before the end of the war. I am proud to remember them.

Viv Baker: I am a first generation Canadian, whose ancestors hail from Plymouth and Walthamstow. In fact the wharf that ferries people from Plymouth in Devon to Cornwall is named Shepherds Wharf... after my great-Grandfather. Today I will be remembering my Grandfather Sergeant Edward Edwin Shepherd who was born in Plymouth. He enlisted with the Canadian Expeditionary Force in 1914. He made it through the war, but on September 30th, 1918 he and the 40 troops under his command were snipered while making their way through Cambrai, France... all lives were lost. Today, I am honoured to attend a special exhibit at the Markham Museum near Toronto, which is dedicated to the memory of my Grandfather and two other soldiers who gave their lives in the service of their country.

Eddie Clarke, Deanshanger: I have just observed the two minute silence alone and thoughtful... My father fought in the first world war and he died in 1953 when I was 2 years old... It is not until recently I learned of this as my mother never spoke about him. But on reflection we must remember all those who served (most of whom are dead now) not just remember those who died at the time. Many more went on suffering for a long time (both physically and mentally)... We owe them all a great debt...

It is a poignant time as both my Grandfathers fought in the WWI, one I knew, my maternal Grandfather who was also wounded at the Somme before returning to active duty as a Royal Sir Corps member mapping above the trenches. I have his flying pennant, compass and binocular as a well as a German helmet he gave me as a small boy. I can just trace the name of the German soldier who owned the helmet, still visible in that thick lead pencil, 'Rosenberg' and a number that I have yet to decipher. I would like to trace him too, obviously a young man who presumably was killed in battle. The next four years will be a very moving time.
