Last night (Sunday, May 21st) http://weblogs.asp.net/ was updated to Community Server version 2.1.
This was a long overdue update, but it brings some great new features and capabilities (such as search and tags) to the site. We've also done a lot to make the content optimized for search engines.
There are still a few issues to iron out, but overall the update went smoothly. If you're a blogger on this site you should have an email from Alex Lowe about the upgrade. Please let him know if you run into any problems.
