Sorry to butt in Lans but I don't have a computer at home and I need to keep up my post count.
TePlayer, this is cRPG, not one of those other silly mods, we have the same standard set of rules across all of the official servers and that says no teamkilling. As much as it's a pain in the arse to be attacked by an ally there are much better methods of dealing with them, specifically contacting an admin as Lansa said, by using the "i" chat.
Losing a round to get the offender banned as opposed to losing a day as you come across as the offender.
At the same time, it's one day, learn from the mistake and everything will be fine.
On a side note, admins tend to make use peoples names to make judgements, what I mean by this having "Cum" in your name practically shouts "i'm intentionally being a twat" and people in general will be less inclined to believe your story. I'm sorry but everyone is human and offencive/aggressive/provacative names etc will only work against you, even if you don't see it that way yourself. Of course, there is nothing wrong with your name but it does influence how things are percieved, I guess you could say it's about your public image.
