Here ya go. With apologies to Dick Gaughan for not requesting permission, here's Rule Two of his forum:

2. No anonymous members.

It is a requirement of forum membership that you let the other members know who you are. There is not a single good reason in a forum of this kind for anonymity. If you are normally known by a nickname, by all means use it here; my birth name was Richard but the only people who ever use that are my parents (both dead) and my two sisters and their children. The no-anonymity rule is not here to check people's birth certificates, it is simply so that we all know who we're talking to and the risk of anonymous trolling is reduced. As said, by all means use a nickname on posts and as your username but please put your real name in your member profile and you will be asked to give it when registering.

"There is not a single good reason". And, if you don't like it, go elsewhere. And it works. The forum can get very controversial, but there's just one active moderator and she rarely needs to intervene (she's bloody tough when she does, though). Good manners prevail. If that's what you want, you can have it. But don't go all "laissez-faire-on-principle" then moan when it doesn't work.
