This compilation is a very large file of about 22 pages. It gathers a lot of cheats, tips and tricks from a wide area of sites. There are quite a few corrections too. Yet, I feel that is not complete, as I was blocked with some of them.
That's why the file is a DOC file. Feel free to add, comment, correct it.

Enjoy, and here is a Zip version:
