This tutorial will teach you something that I discovered pretty recently, and you may have seen being used. Its colored server names!
1. Start a server, if you don't have one running already. Remember the server name.
2. Open the console with the tilde (~) key.
3. Type this into the console...
$Pref::Server::Name = "[RTB] *Color**ServerName*";
where *color* can be...
\c0 - black
\c1 - red
\c2 - white
\c3 - white
\c4 - pink
\c5 - blue
and *ServerName* is your server's name.
4. Push enter, and close the console with the tilde key.
