You can still get WinMX working by editing your Windows host file - I can't remember where I got that info from now, but mine's still (sort of) working. Downloads are possible but there's not so much to choose from right now.
Yes this was a method suggested before, but I'm not sure whether that will still work. The last article I read (see previous post) suggested that it's all finished.
Tis still working with a patched host file, I assure you
