You can't change it so admins aren't kicked, you would need to use SourceMod for that, but if you want to disable kicking of players.[/B]
You're probably looking to set sv_vote_issue_kick_allowed to 0. Add this to your gamemode_xxxx_server.cfg (replacing xxxx) as described above.
PHP Code:
sv_vote_issue_kick_allowed "0"
Thats all i needed. I have bunch od admins who can votekick anyone i just wanted to disable native votekicking and leave native mapvoting. Thanks a lot
