Hi and thank you for your interest.
>First of all, what will my members have to do to use this service? Is it as simple as them opening it up and using it? Without further profile set-up.
Yes, the chat ail be embedded in your site and your members will just have to visit the chat page.
>Secondly, where is this hosted? Is it going to be using my bandwidth.
The chat will be hosted by you on your servers. This will allow you to locate it close to your members which is important for video latency.
Let us know if you have any other questions.
