a user types !voteban and the others say !yes/!no as to whether they want that person banned. The vote runs for 30sec and needs a minimum of 4 votes to run.

There is protection so that people cant vote for themselves and people cant vote twice. An op on the channel can do !end to cancel the vote. It will also work if the user changes their name before the end of the vote.

I am fairly new to scripting so be critical, tell me what u think

Paste code into remotes, then restart your IRC

;Commands:
;!voteban <nick> - sets a user to be votebanned
;!yes/no - register your vote

;[admin] [+o]
;!voteon - turns the voting system ON
;!voteoff - turns the voting system OFF
;!end - Cancels the current vote!
