Usage: UNKLINE <user@host>

Will remove a kline from your server. Note: you must match the user@host information exactly or the unkline will not work. You can use wildcards to erase multiple klines at one time.

/unkline lamer@pm02.digex.net
/unkline *@*.digex.net

This undoes the kline command. It is generally good to remove klines periodically. Klines will often ban people who did not do anything wrong, and people will often start behaving when given a second chance. It's a good idea to keep track of anyone who is being repeatedly klined so that stronger measures can be taken or the kline can be kept.
