It uses the open protocol XMPP aka Jabber. It can do chat rooms (group chats), messaging (IM) and can reach and be reached by other XMPP servers around the world (like google talk). The big advantage over AIM is that XMPP is decentralized. Your messages only go as far as the servers involved, so it saves electricity and network traffic.

These two instances of apache2 serve multiple wikis and web sites. They are located in the Computer Science Department of Vassar College. As a result, they all get the same site certificate. In some cases that works just fine. But in some cases your browser will complain about not being sure if it should trust the certificate or not being able to verify the certificate. text/html 2008-10-24T17:22:31+00:00 Anonymous (anonymous@undisclosed.example.com) https://www.cs.vassar.edu/old_pages/wacom_tablet_tips?rev=1224868951&do=diff Using the Wacom Pen Tablet on our Linux Desktops NOTE: Currently the 5 buttons on the tablet itself are not detected by the windowing system.
