ok im stupid, wheres the shoutbox at???
it's the long box on the right hand side of the main page where you can post a quick message.
also, regarding your question, i'm not sure what the air date of the show is that you're referring to, so it's almost going to be impossible for me to get to it and replace it with a complete show since the archive is so huge. if u happen to hear it in the future, please shoot me a note and i'll get to it.
as max said, you can see a list of the shows that have played already, but there is no list to tell listeners what is coming up. to create such a list would require some work on my part, as it would have to be in real-time and completely automated. i get this question from people a lot, so it's probably worth looking into whether or not there is some sort of winamp plugin i could achieve this with.
