Thanks for all the helpful replies. Dwight - that looks like a goldmine of advice on the subject, thank you. Fist, good to see you again - been a long time.

We don't play around a table, we play around a circle of sofas and my GM table, but it's probably okay. I'll stick the mic on a little stand in the middle. Everyone talking at once... I don't know what I can do about that, but maybe I can use the microphone as an excuse to try and keep some order.

Nah, it wont work. But never mind, losing parts of it is inevitable.
tete That link is very useful - it's good to see the sort of thing I'd need. I could buy one of those if I wanted. I'd prefer to find some way of trying it out first though. I'll see if any local shops carry it.
Does anyone know how much space a five hour recording would take up at a reasonable quality. My friend would probably be willing to host it for me, but I'd prefer to not ask if it's going to use up a lot of bandwidth. I understand if I used bit torrent that would reduce the bandwidth a lot. I have my website on my own server so that shouldn't be a problem, I'm thinking. I've no idea how popular this would be. Some of my PDFs get downloads in the hundreds, rising up to things like the Matrix Examples which passed a thousand fairly easily. I'm looking at an MP3 on my phone which is four minutes long and takes up 6MB. At that rate, five hours of recording would be 450MB. That sounds like a lot. What are the chances if I used bit torrent that people would leave this seeding?
Sorry - I'm asking a lot of unknowns now. Never mind. I'll see if there's any way I can try out one of those mics If there is and it's good, I might try this. The sessions are usually a lot of fun. I'm sure people would enjoy listening.
But video is out. Too much blackmail potential.
