I've noticed that, with Jedi-Master, but what I like about him (or her?) is that he or she seems to not hold grudges after debating with people, which is refreshingly mature on the BBS. It's always nice to have friendly debate rivals, and I'm sure Emma enjoys that too. When you enjoy a good debate, the last thing you want are assholes that act all pissy and angsty towards you afterward.

We really use it to talk to each other because Emma seems to be a mutual friend for most of us. Except Jedi-Master. He sees her as a rival, but in a friendly way.
