A site on tripod is likely no longer maintained. I would be surprised if you hear anything back. It would be great if you did, though. I did a bunch of tape trading in college and some time after. With everything going digital - trading became somewhat senseless. I could post a link to a show - and not have to worry about blanks and postage. If you do get your hands on any of the shows you're looking for - I'm sure you'll put them online.

Speaking of which - this site can totally handle live shows as well. I know you're posting things on youtube - but if you're interested in getting them here in a more collected way - let me know.
