I made a new sticky in the Dedicated Server forum which I think is long overdue.
Many people don't even know what Rcon is, are afraid to learn it or are simply clueless.
However it's not as bad as you think and the system is actually quite useful. I suggest everyone who doesn't yet know go check out the link and read up!

I just want to help improve the level of knowledge of the admin community as a whole. The more you know, the better choices you can make to run your servers more efficiently. But you can't do that without the most basic knowledge of Rcon, an essential part of the MP of all Q3 engine games.
