1 year, 4 months ago: @deairby Hmm, that’s a good question. I believe there was such a possibility to use Facebook for closed group, but I am not the expert so hopefully someone will chime in on this one.
In the past, I have used BaseCamp as a tool to share documents, notes and work with folks who are in different physical locations. And then, of course, there is Google Docs, which is free and universal, assuming you have a gmail account (folks who collaborate must have one as well).
Hope this helps.
