I really hope that OP is correct. Luna must appear in season 2, or I shall be extremely disappointed.
But Luna + Halloween? I don't see that adding up....
If I'm quite honest, I don't really like IPBoard, but I'm sure I'll get the hang of it. It seems to have the same qualities as vBulletin. Also, agreed with OP, this site is indeed quite cool.
Adding new sections, as far as I'm aware, does not increase server load. I have no experience using IPBoard, but separating the sections might lessen any future confusion.
