Once you unzip this package, in it you will find a file

search criteria.txt

which explains something of how I got this information. 
It's a rather large package, mostly because I preferred to save each webpage with pictures, otherwise it might be dificult for you to read and understand it. If you help me clean it up and copy/paste the important information into a single Word file (the formatting should be mostly retained), I can clean that up and then post it for others, so that they do not have to download and read such a large package. 
The package is downloadable from:
http://africa-charity-project.org/free-educational-program/external-files/Donation-request-sample-letters.zip
and it is 20MB in size.
