New to Project 99

[jpetrick]

I haven't played Everquest since PoP and I saw Project 99 was around and it caught my attention. I really wanted that oldschool mmo experience and nothing made after EQ ever was able to recreate how good the first few expansions of this game was.
That being said, how is the server population?
My favorite class was a monk way back in the day. Will I be able to find groups easily as a monk going from 1-60? Or will I likely be soloing a lot and should opt to play a more solo friendly class?
