What are the rules about signatures?

[Mike Ellwood]

Most forums allow signatures. Seems harmless enough. (Unless advertising, I suppose).I don't seem to be allowed to set one. Will this change after so many postings, or what?Thanks.(I don't want to advertise anything, I hasten to add).

at this time I can't post a signature, this happened when the forum was hacked last time.I also can't send messages or look at members profiles?I don't think there are any specific rules.
