Welcome!!
BTW, if you have not finished Angel I would stay away from these boards until you finish it. There are tons of spoilers here, and they can be found everywhere. You might feel safe in Buffy Season 1 Forum, until someone says "Buffy's Death in Prophecy Girl reminded me of Angel siring Wesley in Season 4." (note: didn't really happen).
Season 5 of Angel is one of my very favorite seasons in the Buffyverse. There are several things that happen that are so amazing, and I'm so glad I didn't know about it.
I first came here before I finished BtVS. Someone suggested I stay away until I finish BtVS, and I'm glad I did.
