I think daniweb's social groups should be linked off the main page under "Daniweb Community Features" on the bottom right section of the page pointing to: http://www.daniweb.com/forums/group.php

I can't remember how I found the groups but the only way I can get back there now is by viewing my profile, clicking on my group, then clicking back on the "Social Groups" link to see all groups.

There is no "DaniWeb Community Features" section in the sidebar. There is a "DaniWeb Community Feedback Features" that you see because you're in the DaniWeb Community Feedback forum. If you were in the C++ forum, it would dynamically change to C++ features, and so forth.
