This is/was our fork of AJAX Chat from back before the Sock Chat days.
I'm pretty sure it's based on AJAX Chat 0.8.4 but I'm not sure. It's probably kind of impossible to run this fork yourself, not that you'd want to anyway.
Unfortunately AGPL requires I use the same licence for my additions so you'll have to deal with that. Also AGPL requires me to include the full licence text, which AJAX Chat didn't actually do itself so I'll do an attempt at recreating it.
There's probably a bunch of copyright violations in this repository but I don't really care.
I'm providing this pretty much as-is, aside from the adjustments I will be making to make this run on ajaxchat.flashii.net for preservation of the Classic experience. If you review some of the Language used you'll understand this disclaimer, however historical accuracy is of utmost importance.
