Best ways to get new players are toplists. I voted on the button at this page but its hard to check out what to do when it isn't in english.
1 of the best toplist is hopzone (http://l2.hopzone.net/) if you at this server there we are under new server and all player which are looking for a new server will see us at first. So we will get a good community and a lot player.
And all what to do is VOTE VOTE VOTE
