I wonder which GUESTanon that was? I mean, some anons are ok, some aren't, and it's hard to tell the differenmce between people when they're invisible. Why people don't just use a pseudonym, when they want to preserve their anonymity is very puzzling.
Since anyone who is a member can be contacted by Personal Message, I'm not sure what the point of having email return addresses - unless the idea would be to stop people posting anonymously, which seems a strange request from someone who wants to be able to post anonymously.
