I mainly make lessons and animations for math and science. I am also the original author of the Guide to Huxley's Island.
I made a program that converts html format to wikibooks format. It's pretty simple at this point but can save a lot of time. It's written in Visual Basic 5. If anyone wants to use it, wants the code, knows a place I can/should post the code, or knows a better program that has already been written, let me know. My program handles bold, italics, wikipedia links, and page breaks.
