No restrictions...basically I got roped into it because I'm a Librivoxer, so I've run classes in Audacity before. Now I need to show people how to set up a podcast from soup to nuts, which is something I've never done. So, I need to do it before I need to develop a program and teach it. What I use to develop the skills doesn't matter from a library perspective.
Personally, because I'm not working on anything RPG related right now, I'm a bit out of it in terms of topics.
Yes, I am a librarian, and yes, my library does free interlibrary loans across all Australian members of the national ILL system, so, sure I can get most stuff. Lacking anything else I'm going to start strip mining Thomas Costain's books for ideas, because we got so much out of The Magnificent Century for various Ars books.
