Do any speakers have recordings of their presentations, on audio or MP3?
If anyone doesn't, it could be quite easy folks. As most of us are into laptops and Powerpoint-type programmes, every laptop has a microphone. Also, there are some free programmes out there (the best of course will be shareware and have limited options until paid for) that will record your desktop, like a movie.
Something to think about on an individual basis?
