I don't sign my name because I am paranoid about being in such a venue for the first time - never been in a forum or chat room or anything like it before. I've heard and read about internet horror stories which, of course, may be urban myths. However, given the choice, I prefer to remain anonymous, especially when there are so many anon's' in this forum and since non-members can post anonymously. If the rules change to incorporate some kind of certification of membership and security system, I'd be happy to sign my name. Until then, I'll follow the lead of so many others before me who obviously must have good reason for anonymity.
