The beta is on for the next version of Google Groups. Not only does it look a lot like GMail, when I go to the site, it logs me on with my Google GMail account ID automagically. I can mark topics with a star () and then click on the "My starred topics" link to do a quick search list of anything I've previously flagged with the star - a lot like the way it works in GMail, go figure.

Plus, I was able to create a new group right there on the groups web site, in about 2 minutes. Worth keeping an eye on.
