I saw this over at the ItsMods site:
Basically, someone has recompiled the server files and gotten logging and timed messages working. There is even a plugins feature, but the example plugin provided is a unlimited ammo hack (which isn't good). However, the possibilities/potentials are endless.
I haven't tried this, so use at own risk, but I will say, the stuff provided by the Itsmods site is always virus free, and most (not all) is good stuff.
