Automatic MUC Moderators

Hello,

I have a question regarding ejabberd's MUC module mod_muc

I have created several MUC rooms for specific groups of users. I want certain people to be automatically set as room moderators when they join a room. I do not want them to be MUC admins, only moderators. I know MUC admins are automatically made room moderator when they join a room.

Is this possible?

Thanks,
Alkemist
