Can I do this with CB 1.7 with or without plugins?
Or will it be possible in CB 2.0?

I need to assign groups of users to sub-admins. This is useful if you have an national organisation with a number of local affiliates that use a shared member database where users are not allowed to manage all their data by themselves.

At national level, the top level admin should be able to manage all members/groups.
On local affiliate level, the local admin should only be able to manage the users assigned to him/his group.

Habe my explanation was too poor here...

the point is that there is a layer of moderatiuon missing (in fact, so is for all community components ).

Not all communities are of that kind that you only have only Site Moderators and Users (like here on CB Community) There are lots of communities where you need to divide the community into smaller managable groups, and you cannot let users edit all their fields.

Maybe a school is a better example:
1. The headmaster can access and edit all students and all their fields.
2. The teachers can access all students in their classes, and edit stundent´s fields like address and grades, but not edit some other fields.
3. Students can only edit their address.

As described here, admin as in pt 2. is missing. Having that feature would make CB far more flexible.

Hope this post better explains my question/idea.

Hi,

Is it still too eraly to say if 2.0 will have the capabilities discussed above?

This could also be solved in 1.9 for frontend editing with an extra plugin, but will plugins for 1.9 be compatible for 2.0? Or better wait?
