I am a designer and would like to add a chatroom with ability to design it so it will look like my current site design. Lately I added a chat room (text chat) that let me add YouTube videos and images. This made users stay longer. The issue is that I cannot integrate my user base (I have around 1500 users) to the chat room and all need to re-login. I have checked both 2 good services RumbleTalk chat and c-box chat but then the lack of 3rd party users integration is a problem, any recommendation?
