Only thing i would change is the file your telling them to get. The reason is existing installs means existing WMG patch installs.. so its best to get the Various WinMX Version and Patch, however .. its important to select the current version when installing so firewalls dont cause headaches over version changes..
Not sure how to word that for a pm..
If your winmx does not say patch operational , top left then go to http://www.winmxgroup.com/downloads.html
and download and install Various WinMX Versions + Patch, choose your current version when you instal.
This will be of benefit to you and also the whole winmx network.
