// @namespace   http://www.dragongoserver.net/goodies
// @description Add the red "new" indicator to forums with new messages.

 Known bugs:
   When you post a message, the "new" flag will be set because there
   is a post in the forum that is newer that your last entrance.
   This could not be avoided. Just re-enter and quit the forum.

 Tested with
   Win98 + FireFox 1.0.7 + GreaseMonkey 0.5.3
