Reader locations

I've put up a little survey / poll on where people are. The reason I'm interested in knowing is to work out how many people might come to a London / South London event if I could arrange something like that. I'm thinking along the lines of one of the CDM events.

UPDATE:

Sorry, I left out Europe! How could I forget!!!!

2nd UPDATE:

I had to take the poll down to add in other locations, so please accept my apologies if you'd already voted. Please vote again and I hope I haven't missed anyone off this time!
