A user who gets the sticky status can't do more than sitting in one special channel. Even admins will loose their permissions while sticked with this module.
This script is a port to MuMo of https://github.com/Natenom/murmur-sticky.
The Script and the .ini-File can be downloaded from Github, see https://github.com/Natenom/mumblemoderator-module-collection-legacy/tree/master/sticky.
This script uses temporary group membership because you can very easily fuck up your server :P
