Hey sgeepy,
In addition, the Lordaeron realm was just recently launched (less than a month ago) so i would strongly advise you to start on this realm. The Warmane staff will release content progressively. Right now, Lordaeron is like vanilla wow - level 60 cap. At the begging of november of this year, they will also release The Burning Crusade content, and, some time after that ( a couple of months), Wrath of the Litch King content.
You should also know, the Random Dungeon Finder is disabled on Lordaeron, in order for players to go out into the world more, explore, find each other, create groups and actually traveling to the dungeon's entrance.
Cheers !
