some mp3 players have voice recording and from there you can download it to your computer and drop it in an e-mail.
if that's not an option, there are many small programs that can record from sound devices on your computer's mixer. the one that KBF posted it an example of one. i'm sure you can find plenty of programs on http://www.download.com if you do a search of 'mp3 recorder'. just watch out for the trial versions that only record for 10 seconds tho :lolsign:
