Did you ever find out about this? I'm looking for a document collaboration environment too. It looks as if huddle, bob.net, and others are all gone. Anyone have further intel?
Of course this is gone! I looked too! This is why Ning needs to build their own stuff! I just posted something about making a group completely private which would at least give member a chance to share and collaborate privately w/o Google swiping it. HELP US NING!!!
I'm James from Huddle, unfortunately we had to remove our Ning app because it was too technically costly to maintain. Anyone who has the Ning app can claim their Huddle account through a small link in the bottom of the app page called "Go to my.huddle.net". And if you would like access to your data but have deleted the app, just let me know on this forum.
Sorry for any inconvenience caused,
