Looking for demo editing help

Well, technically, everything related to demos in general. I have a lot of cool ideas in my head for various movies but am a noob at demos. I don't even know how to record them! So could someone please give me a name or link of a place I could go to improve my noob demo editing skills?

There are guides in the Player Guides section -- do a search on "demo edit." here are some I have favorited, but haven't updated the list lately. ("Lately" meaning "over a year.")

Zloth's FAQ.
Majik's guide.
Storm Knight's guide.
Zloth's page o' goodies.
Djeannie's in-depth thingy.
