I am helping a volunteer group that is in Australia and NZ. They want an area for members only - easy enough. Members should be able to see content across the two countries.
Different cities have local chapters with their own meetings and events. They want privacy for regional committees to keep their board meeting minutes private to their group.
Is this possible using any free CMS plus some add-on (paid is OK if not too dear)?
I can visualise something like aMember Pro working for members, but not where different groups want a higher privilege to different areas. Suggestions?
