I know that several CofC Faculty became quite accomplished Ning users only to be cut off when Ning decided to cancel their free service.  Well I just ran across a potential substitute called Toonti.  It offers many of the same features offered by Ning and it worth checking out.  I was never a big Ning user so I haven’t tested Toonti out very thoroughly so I can’t attest to how similar it is.  Take a look and let me know what you think.  Is it as good a Ning?  For those of you who try it I look forward to reading your comments here!
