Starcraft II Beta?

I just went and pre-ordered this title from Gamestop today for the sole purpose of getting the Beta key.

Anyone else have Beta access to this game yet (either directly from Blizzard or through the Gamestop promotion)?

If so, I would love for one or all of you to beat the crap out of me some time. I'm a huge fan of RTS titles, but I haven't been good at them since like 1999.

I've been playing for a little over a month now. I pre-ordered at Gamestop to get the beta, and then Blizzard e-mailed me and invited me again! Doh.

It's pretty fantastic though. I'd give you my tag but I haven't been on since the wipe two weeks ago where they added 3v3 and 4v4 matches.
