Anyone know of any good free chatrooms there is available to embed in our forums ?
There's the
SpiceFuse AJAX Shoutbox. I don't know if that's what you're looking for but it's the most popular shoutbox to date.
Something i can embed into the forum itself.
Yes, an IRC channel then.
IRC would be good but it's usually javascript and not fun. I would go for just a shoutbox personally.
