Note: Do not advertise a cast if it isn't even online.

Anyways, trying to upload a cast via a forum is a bad idea. There are several audio hosting places. Be sure to pick a place that lets you stream at, as many wont want to DL the actual file (some will, of course).

Heh, Just good luck is all I can say. It's hard doing audio casts that are interesting and worth a listen for a big audience.
