How can you join? I would like to talk with those posting, and ask questions as I wait for the console release. Sadly, no matter what I do, it says I need an invitation number. What gives? I have preordered the game, if it matters.

Basically, you must own the game in order to actually use the forum. Once you make an account on TESO, you should get an invitation code or whatever. It's to prevent nincompoops that don't own the game from trolling the forums or something like that.
