You do not need this file if you have updated to Version 1.20. For Version 1.10, the non-gilled descriptions give sources that are not in the main help file written for the Gilled program. You can download these sources in a separate help file, which is placed in the folder
C:\Program Files\MatchMaker\

After you download mmnew5b.exe, double click on it. (Running the program from the website will not work.) This small program will ask if you wish to unzip the files into
C:\Program Files\MatchMaker\
Click Unzip, OK, Close.

To read the file, called Nongilled Sources.hlp, double click on it in the folder just mentioned.
