Groove 2007 hotfix is coming - fixing 2 very annoying bugs

#1. Account restores: Used to expire after 60 days and could not be imported. This hotfix allows account backups older than 60 days to be used.

#2. Fixes cases where auto configuration fails.

Right now it isn't a public hotfix but there is supposed to be a service pack released pretty soon.

Another cool Groove related item I found on the same page was a Groove backup program and a Groove RSS feed creator for threaded discussions within your Groove site.
