Hey there..
Firstly, please mellow. Secondly, sorry to hear you've got a ban from a server. If you were vote-banned, the ban should expire in 12 hours. If it was a server administrator, you'll need to contact the admin of that particular server. Please
read this thread, and follow the instructions.
If you can't find the information you need on the particular server you were banned from, send me a PM and I'll see if I can track them down for you. Ideally, if you have an MPR which would vindicate your behaviour on the server, it would be a good idea to keep that handy. If it was the last race you were in, it may be stored in a file called "temp.mpr".
Hope that helps..
