The following is a gzipped tar file of the site-lisp directory on my personal computer. It does not claim to be very well organized or anything, but you may find some of the stuff in it useful. It is very strongly oriented towards minimizing the keystrokes.
If you have installed Emacs on Windows 9x or NT then you will have used gunzip.exe and tar.exe to unpackage it, so you can use the same programs to unpackage this file.
