Because I feel that it's more of an American site and I'm in the UK
You know ecf is now being run by a brit, Chris Price (rolygate). It was only recently that the previous manager, an american, retired. ECF was founded and is owned by a brit .
If you don't like the fact that there isn't enough of us brits here then that's one thing, but if you close your account you won't be able to open another one, meaning you won't be able to ask questions, ever !.
But if you feel the need to close your account, not that it would make any difference apart from the fact you won't be able to post anything, then click on the little yellow triangle at the bottom left of one of your own posts and ask for your account to be closed when the next window opens.
