Time for me to be a party pooper. I frankly just don't see a need for a PVP forum. You see how often the other sub-forums for EQ2 get. Most people just just the General Board here for everything due to the closed-tree architecture of the boards here. A PVP forum, both being a sub-forum and given the amount of PVP posters we have, would get one or two threads a month at best after the initial flurry wears off. You'd get better response opening PVP-based discussions here on the general board.
That said, I don't see any real reason not to have a PVP discussion board added either. It certainly couldn't hurt anything and it would make the boards appear more complete.
