Well, I can show you a basic setup of recording audio and video from the browser and playing it back... what I originally wrote (some time ago) is more like visual email. I can adapt it to what you want. Then, if you like it, we can work to integrate it with the forum (I'm not real sure about that level of effort, but it is completely doable and I"m excited to do it)!
We'll have a lot of decisions to make at some point:
1) Who should be able to do it. I'm just thinking of limiting to be people we know are positive people we want to get audio/video from.
2) Media storage.
3) I'm sure many more.
I have a lot of time next week and, btw, I've got a couple of weeks after bootcamp in Wales with no particular plans. Maybe I could work with your tech guy a couple days while I'm there?
