Messages don't work either, that's why I'm writing here.
Have you noticed that our networks have not been working normally for two weeks now, and are only displayed sporadically? Two days ago I contacted support for three hours! They gave me a ticket with no number and I think they are all just running Ning 2.0 without support to push us to Ning 3.0.
What do you intend to do, how to react? Because your network are also affected.
