I need a free networking / collaboration platform, which will be usable by a small non-profit organization, where most members are non-techno. So they handle e-mail OK, but struggle with online forums etc.
I want to be able to share files, hold group discussions and provide an event calendar to which everyone can contribute with not too much complexity. I also need to be able create and edit user accounts and configure notifications as the admin, rather than depending on group members to login and configure their own settings.
Something that lets people do as much as possible by e-mail, without needing to login often, is what I think we need.
So far we've tried Google groups, Google sites, Ning & Buddypress. All have proven too complex for our non-geek user base.
Can someone suggest something? Thanks.
