We use the Ning platform to run the Ride for Roswell community site (RideConnect) and for the QuantumCMS forum (QuantumCMS is Algonquin Studios‘ web content management system, for which I am responsible, so go sign up with us). Having access to 90+ applications should prove useful to these sites. Sadly, I can’t offer much commentary on them since they just launched today. The complete list of Ning Apps is available at the Ning Apps Directory.
Ning has set up a sample site for the apps at ningapps.ning.com so users can try them out.
