which permission should i add to have experimental in sire administration...
i don't want the user to be allowed to do every thing so ignore the following permissions:
1. Allowed to do every thing
2. Change site configuration
Well what exactly do you want your user to be able to do? (what do you mean by experimental?)
i want him to be able to make the actvity of the course being taken by group, so to enable this option i need to go to site administration->...->experimental->Enablegrouping
Well once you as site administrator have done that, then any teacher can use groupings in their course. They can already use groups without any extra permissions. I suspect you don't need to change permissions for teachers to do most of what you need them to do
