I don't know if is useful for anyone but I went to leave candles at each of the bomb sites this afternoon and discovered the following
Kings Cross: flowers/candles/tributes are being left in a cordoned-off area in front of WH Smith. there was a police officer and a member of the Salvation army looking after it and they were really sweet (asking if I was ok, if i knew any of the victims, offering me a lighter when mine broke).
the only problem was there is still a huge press prescence there. As soon as I walked into the area to leave my tribute, cameras started snapping, i couldn't look to the left or right because I knew there were big banks of press watching me do something really quite personal. When i wiped a tear from my eye, I could hear the cameras snapping faster. I don't really resent this - I know from reading my friend's list on here that people all across the world want to know what's going on, but if you're still quite upset by the whole event it may be quite a distressing experience.
Tavistock Square: the entire area is still completely roped off, and the police looking after the entrances innitially told me there was no where there I could leave tributes myself, but if I wanted they'd take my flowers over to the church (forgotten it's name - the big one on the corner of Euston road). However, after a bit of wandering round I discovered that people were leaving tributes in Russell Square Gardens (map

I'm not sure about Liverpool Street or Edgeware Road.
Also, according to the
bbc there will be a 2-minute silence observed next thursday at midday, though plans to specify a place in London where people can gather have yet to be confirmed.
