Welcome to Google Groups
http://groups.google.com/googlegroups/overview.html
Google Groups is all about helping users connect with people, access information, and communicate effectively over email and on the web. Now there's a new version on the block. We didn't want to say it, but yes, it's new and improved.
It's got a new look, and there are a lot of great new features. If you're already a Google Groups user, we think you'll like it. Just sign in – all your groups are already there, just waiting for you. If you haven't tried Google Groups yet, why not search, join or create a group? Or better yet, do all three.
