Thanks Paul,
While I'm listening. I take it you use Elluminate for all the live sessions. Do you use any others? Do you use anything like Skype for a quick informal chat? I hope you don't mind me popping in from time to time to ask questions like this. I'm just working my way through the (open) infrastructure that OERU (and quite a few other secretariats) will need with the guys who run your National networks. Here's one.
I gotta say though, as far as the first credential is concerned, I still think a Masters of Comms (global) would be a natural. I know credentials are important, but most students i know just want a job.
Funny part is that you don't have to do anything more than what you're doing here. I point my silent geek friends at this domain and just show them how a community is (being) built. All the best.
