As I said way back when, I have no desire to Chat; I don't want the added complications of receiving PMs, (because I want everything that's said visible to all, and I probably wouldn't have the time to give individual responses); I want nothing to do with the Rep System (because it is very inaccurate and unscientific and attracts loons); and I don't see registering as providing my name any more safety from identity theft or making me non-anonymous.
A few others may like these features, and that's OK, but I don't. Sorry.
