Hello!

I hope I am in the right place to ask this question. I am researching which chat application I should use on my site. It is algo trading website and many customers suggested that having a chat would have a great benefit.

I want to be able to post charts and youtube videos there and I as well want to have it in black colour as it will go the best with my site.

I already found ********** and Envol but still making research to get the best option for me.
Thanks!
