ChatWing is a product that I've reviewed before, but was asked to take another look at it since they've made a lot of changes. It's a nice site - you can create your own chatroom really quickly. New functionality includes the ability to include video straight in the chat box, as well as images and hotlinks. You can also password protect chat and force login and change styles. It also supports 9 different languages. I tried it out yesterday, and it's quite impressive. I shall be using it on my multimedia courses!
