I got an e-mail today from the Office beta team reminding me of upcoming beta expirations. Here are the key dates:
Beta 2: February 2, 2007
Beta 2 TR: March 31, 2007
Server Beta 2 TR: May 15, 2007
Your options are: attend a launch event and get a free copy, download the 60-day trial, or download the Office 2003 Compatibility Pack. But you'd better do one of those soon.
