Welcome to the community, here's your initiation:
Read the how to play guide if you haven't done so already.
If you want to play a legit server (that means something like EQLive), I would suggest either Dynasty or Scorpious2k. But keep a sharp eye on Guildwars, it is currently down but is widely agreed to be the best server out there.
Also there are Non-legit servers (servers that everyone has GM powers) and Semi-Legit, where people have only selected GM powers.
And only servers that run with version 5.3DR2 will work.
I've only been here for a couple of days so thats the best advice I can give ya.
