I am currently creating the group chat system. At the moment it needs a bit more work, usernames don't display properly. I will hopefully have it in place by the end of the week and then the message chat plugin will also have a makeover as it looks messy to me now.
I have also added a temporary fix for the scrolling issue in chat whereby when it is loading previous messages it sends the user straight to the bottom of the chat. I have added a load more button every 15 messages so that it has less to load. I will fix it better in time.
