I just set up docs to see if it will work for an organization I'm involved with.  I'm impressed with its functionality.  But we don't have much of a budget, so we would prefer to make do with the "free" level.

 

Looking at the comparison between levels, it says that free doesn't offer things like check-in/check-out, workspaces, group management, etc.  But I have all that now.  Is this a sItuation where I'm getting the top level free for a limited period, and then they'll take all the features away? 

 

Anyone out there know if that's what is going on?
