I'd like to point out that there is a good web-based help file that explains in simple, basic terms how to do some of the nifty stuff Calibre is capable of.
http://stu.wccnet.edu/~rprice/Eng218...Help/index.htm
It also explains concepts like metadata (which I don't think is really all that difficult a concept to grasp).
If it would make things easier, I'd be happy to share the actual files with anybody who could make the help file easier to find. I'll also take any suggestions on how to improve it.
