Users of our Facebook messaging application Chit Chat for Facebook are required to update to the new version of Chit Chat. We've introduced some important changes to our application to ensure that it works with Facebook's new processes.
Today, you will have discovered that you were unable to login to Facebook chat using Chit Chat and you would have instead been invited to register for a new Facebook username even if you already had one.
I apologise for any inconvenience the downtime has caused and I'd like to take this opportunity to thank you for your continued support.
