I happen to think that Cosplayers are really cool. Well particularly the really good ones but ya dont have to be that good to put a trekkie costume together.
Britain is hardly the Cosplay capital of the world, heck I am not sure most people know what it is. With 12 days notice on what could be a freezing cold, wet, Valentines Day it's a good job its a small bridge :p .
If there is a smaller than anticipated turnout, the chances are that somewhere in London there is a Bomb Scare.
I not joking on the Cosplay being very cool tho. I might decide to go but what time do people have to be there?
