I had a pretty frustrating first day, unfortunately. I got three crashes to the dreaded Error #132...after the first crashed I learned that Blizzard enacted the queues, unfortunately, so that made it more painful.
That said, I was able to get on two more times...I ended the night level 9 human priest and hooked up with my friend (dwarf) in Ironforge.
Overnight, I reinstalled on the hard drive I used for the Open Beta and tested it for two hours this morning.
/me knocks on wood
I was able this morning to play without issue...additionally, the East RP game actually felt like a RP server...refreshing.
FWIW, I've got some write-ups and screen shots on the site linked in my signature.
