I like the one I wrote about, four years ago or so.. and it has auto op, plus a toggle to op anyone who doesn't want to be a full time op. It could come in handy for when all the ops have left, so you can toggle yourself as an op and help control the chat.

Its the part on the beginning: on 100:TEXT:+aop*:#:{
It will check for users on the User list if they have the level 100. If they dont nothing will happen if they do It will work so not everybody can use it only guys who just got added to the bot with the level 100
