@nlafferty I am still actively using @withknown, both personally and professionally. The private communities I set up are still actively being used by many in the group long after the original course was over. A few have set up their own individual sites and migrated their content out as well.

Another option that may be interesting is setting up a community space that people can be a part of natively or which they can have their own individual sites and syndicate their content to it as necessary or desirable.

If you'd like to chat about it I'm happy to do so via phone/internet/other. I suspect you might find some value in conversing with the folks at Known directly as well.
