National groups

Hello everybody,

what about creating national groups? They could be used as a reference for finding people/collaborators for national projects and/or for any other regional issues. Sometimes it is difficult finding good collaborators if you are thinking to inter/multidisciplinary projects and you are looking for experts in different fields.

I would like to create the group "National groups" and then subgroups named with the country name, but I could not find the way for creating subgroups, anybody could help me doing it?
