As far as I can tell it is possible. Have a look at the chanserv commands related to this, use:

/chanserv help levels

and

/chanserv help levels desc

and

/chanserv help set

You don’t have to type the /chanserv part if you use the private message window that opens when chanserv responds. 🙂

Anyone else used these commands before? Please jump in and let us know. 🙂
