I don't know whether I've mentioned this before (a search seems to say no, but who knows?), but some friends of mine and I are creating a radio play based on SR4.
We've got most of the principals cast, but we need more voices for single-episode and incidental parts (e.g. Mr. Johnson, bad guys, etc.) and also for a newbie runner that will be joining the team. I should also mention that we wouldn't be paying you; we're doing this because it's fun.
If you're interested in auditioning, send me an PM and I'll get you started.
