How does one get on the XACT beta program I went to
https://connect.microsoft.com/availableprograms.aspx
and it is not listed there. I signed up for the DX beta program, but it apparently does not let you access the XACT beta newsgroup, which is where I would like to ask questions.

XACT Beta?

I would wait a few more days, the beta newsgroups have been removed and moved to here. From the last few messages in the group the Xact system will go RTW (Release to Web) with the next SDK which should be out any day.

I also tried going to http://beta.microsoft.com/ and using the Guest ID: XACTBeta,
but once I was logged in no beta programs were available for signup.
