From the WHS Blog:
Another 10,000 invites
We sent out another 10,000 Beta 2 invites and in less that 4 hours over 5,000 people have activated their Connect account for Windows Home Server. We still have a backlog of people that want to get into the beta and we would love to get everybody in ... we are inviting people in batches so we can handle the issues that people have with getting access, downloading, and the initial feedback that the new participants provide.
Thanks to everyone for all of the great feedback, bug reports and suggestions via the Connect site. One request from the product team is to please search the bugs & suggestions on the Windows Home Server Connect site prior to submitting a new bug or suggestion. As it takes us time to resolve the duplicates, and we would prefer to have everyone voting and ranking the same bug and adding their comments to that bug so that we can easily understand what our beta testers think is the most important bug or suggestion.
