I made a lot of research in finding a chatroom for my Algo-Trading website. I used envolve for a while till they closed up, pitty. I tried IRC but I truly did not like the look and feel and the "mess" of text in there.
So I went out by myself and did quite a lot of research on it. I will post my results here as it may help to someone in the future.
I had several points which are important to me.
1 - First I needed a chat that can be seen in mobile (all versions) so I narrowed down the search for html5 chat room that look good on both mobile and pc.
2 - C This was very hard to find (my site is dark).
3 - I do not like to install the chat in my server as this is high cpu and resource consumer. So I need a chat service.
4 - Lastly, I needed the ability to add youtube videos and upload files (technical analysis).
I have checked several chats and only 2 met my needs, RumbleTalk and Cbox.
I choose RumbleTalk finally as it can be integrated into my page and not only as toolbar.
I hope this overview will help to someone who will have the same problem.
