European RTS Community Manager Stefanie "Xordiah" Gwinner has prepared the forums with sticky threads with general information, including forum guidelines, beta FAQ, latest news, patch notes and an official welcome thread. Other forums in other languages seem to have the same pattern.
The North American forums had a couple of posts reporting on some bugs, but the threads have now been deleted. It could just have been some random goons posting there, or it be Blizzard posting to try out the system.
Rumours has it some people are receiving their first wave of emails for the beta release, but nothing has been verified.
As of now, there are eleven days and fourteen hours left til the end of February. Blizzard revealed in their press conference call on February 11 that the beta is to be released this month.
