Hi Ben

Welcome to OT! There’s really no rule to distribution here, and it’s very much particular to individual projects – your best starting point is to look up the thread on the work you’re interested in, and see what methods are discussed.

In the case of bigger projects, like Jambe Davdar’s or Adywan’s Star Wars releases, there are usually healthy torrents available for quite some time (Myspleen and Demonoid are favourite trackers around here).
More ‘classic’ Star Wars projects are best found via newsgroups (alt.binaries.starwars is the best source by far).

Beyond that, your best bet is simply to ask someone to send you a disc! There’s no harm in posting a message in the relevant thread and asking for some kind soul to volunteer a copy, or otherwise directly approaching someone who you know has it. In either case, you’ll want to use the private message function at some point, so make sure that’s switched on.

Most folks on here are good guys, so if you’re nice about it (and you clearly will be) you should have no trouble tracking down the stuff you want. Of course, it doesn’t hurt to have something to trade, but I’m sure your music discs will come in handy there…

Hope that clears things up a bit! Happy hunting…

Jon
