From 7392c79fff9e408331844fcfb9dc6e6533ebe3e4 Mon Sep 17 00:00:00 2001 From: mid Date: Sun, 16 Jul 2000 11:10:07 +0000 Subject: [PATCH] - Sun Jul 16 11:03:28 GMT 2000 - Fixed 0001/000a chat printf. (Actually a one liner a few days ago.) - Started integrating josh's 3k rendezvous patch. Currently only directim is working. And its got bugs. But he's not online right now, so I can't bitch. I'd love to bitch here, but I'm tired. - Can definitly accept directim connections and send/recieve. - See faimtest for the new callbacks. (Urg.) - Here weeee gooooo.
