Hi,

just a suggestion for a new Oxwall version - or any interested plugin developer:

It would be COOL if Groups would allow the creation of Groups within Groups, creating a sort of hierarchy. 

Group A

  subgroup A.1

    subgroup A.1.1

  subgroup A.2

Group B

  subgroup B.1

etc.

members of subgroups could be ONLY members of the mother group.

That would allow creating a group "Programming Club" with subgroups "C++" and "Ruby" etc.
