I signed up for the WoTLK beta version at blizzard when I saw I could, got invited a few days ago, already started testing addons. Seems invites are very random. So just keep hoping and sign up at blizz.

I got a beta invite as well, but Blizzard havent yet opened up for addons. So if you got a way to enable addons, please let us know :-)

Addons are enabled. I've been testing a few myself and making small changes to get some to work with wrath.

DF PTR is up so not a big deal; but would still like the opportunity to see the new systems and integrate my addons with what i can't see on PTR, i.e. the actual new content etc.

Disappointing their social platform communicator keeps dropping the ball on addon authors last couple xpacs.

Cheers!
