There’s some new features in development that should make Mibbit even better and easier to use. We’re just working on the finishing touches.
A couple of features that snuck in while you may not have been looking – errors/alerts now popup in a lightbox modal type dialog, and you can setup your chat to look a bit more rounded (Not in internet explorer) 
We’ve also been spending more time to ensure that Mibbit stays up – even if the hosting co decides to reboot all the servers
Also hit a nice record today, of 8,500 connections on Mibbit at the peak today. Possible we could hit 10,000 by end of year. Thanks again to everyone who has helped realize the vision of Mibbit so far, there’s a lot left to come
