you could probably do with learning to post first.
what kinda sig do you want? a banner/picture, or just text?
when logged in, go to make a post, maybe a response in this thread, at the bottom you can tick a box that says 'include signature' and then below that, tick the tiny wee + symbol to open a box to put your sig in. once you make that post, it'll remember your sig
