There's a lot of teamkillers lately, the type that does so for a whole match ("~~~~" anyone?) It's too inconventient and takes way too long to mail an admin. the old DOD had this nice GUI menu where you could start a votekick via the console, then a menu would popup for everyone and all the others had to do is press "yes" or "no".
Would be a nice feature for a future patch.
