first upload to the archive...
i find it easiest to use a ftp client (smart ftp is free)...
make a favorite with the addy of "audio-uploads.archive.org" (without the quotes), and set to port 21
use the login/password that you use to login to te archive...
then you have to import the show via the link that you can access via the
archive.org > "arrange an upload" page... but you cannot import the show until the whole thing is uploaded...
i hope this helps.
