43 of them in all
I have checked all of them and they do seem to be working as of the time I am making this post. lol
If you have problems connecting to them, then best that you contact the server admins. They'll best recify them. Most of them do not have help sites or forums. so you'll need to contact via winmx only.
If you'd like to host your own servers as well, then the most common tool used by people is slavenap which you can get from 
www.slavanap.orgThere are tools avaiable that will get you lists of working servers. But they do not seems to list all the servers that are there.
https://forum.winmxworld.com/index.php?topic=3918.0.htmlYou can get Gotnap for there. It's a great tool for finding working wsx files
http://speed47.chez-alice.fr/napmx/index.php?page=downloadis the link for Napmx. Another good wsx generator
You can even find some servers via google.
If you know any server that are not listed. then please please please Pm me and I'll add them with the person who sent it to me. Any information needed or help, then please visit the tutorials or start a new thread.
