free cross site chat box html widget nice.

Thats right you can add the html code to widget and show that widget on all pages and the chat box will be there, you can be in the forums on your site and chat with people on the home page.

go here  http://bluewavegaurdians.guildlaunch.com/ to get a look at it and here http://xat.com/ to get it.

Trust me its a must have for any site.

EDIT: forgot to add you can have a sister guild on any website and add there group to your chat as well.
