It looks like Diigo has some nice tools for educators, and it advertises similar functions for companies, but I can't find any info on how to implement. If I create a private group, and share bookmarks I've marked private to that group, will members be able to see it? Same with private comments?

Also, tags don't seem to be viewable in the group view? If I want to collaborate privately with colleagues on various projects, how should I do this if they can't see the tags?

I must say, there are no support files for "My Groups" -- it points me here -- and I'm disappointed in the lack of answers/support on this topic here. Hopefully someone can help - thanks!
