My suggestion would be to first check out the sub board for the Siren server. It will be a good source for actively recruiting FC's as well as information about that server's community. If you are looking to transfer or start a new character someone else then there are a lot of options. I don't know if one server is better than another for new players, I recently started 3 weeks ago and picked Leviathan as it seemed to be a more populated server, but more populated may not always mean the best.

If you do end up on Leviathan I would check out the for post for the FC I joined - http://forum.square-enix.com/ffxiv/t...ffs-Recruiting. Lots of friendly and helpful people especially for new players.
