Yes indeedy, we've instituted a chat feature. Something we've had on the radar for awhile now but just got around to deploying. This is just the initial version to see how you CBMers take to it. It will soon have extra features such as private chat rooms and facebook-like friending. This beta version will allow you to chat openly with all, or privately by typing "@username" in front of the message you want another user to see in secret (The message appears in green to let you know that only you two recipients can see it.).
Play with it for us and let us know what you think.

Get ready to see a CBM site revamp which will blow your minds. We'll be taking CBM into the next stage of its evolution and bringing you along with us for the ride. We want to surprise you with all the fun new elements, so I won't reveal everything yet, but you can expect more robust community elements, detailed profile pages along with your fansites, and a lot of competitive fun for contributors to the site--like a "contributor's hall of fame". So, if you're not already contributing, you might want to get involved now. Regular contributors (who set up their Advertising management areas) are making over $1,000 per month with Google Adsense.
Lots of fun stuff, so stay tuned and be sure to give us your feedback.
