I use MediaMonkey a lot, but unfortunately (for you) only on one computer. I believe MM stores its playlists in its custom database, which is local to each computer.
However, you should be able to do the following:
- Make sure (in the View menu) that you can see the Tree pane.
- Make sure (in Options -> Library -> Filters & Views ==> Configure) that Playlists are shown in the Tree nodes.
(The above two steps only need to be done once, if MM is not already set up this way.)
- On one computer, create a playlist.
- In the tree, right-click on the playlist you created and select "Send To -> Export as .m3u playlist"
- Save the .m3u playlist on the shared network drive somewhere.
- From MM on another computer, do "File -> Open" and select the saved .m3u file. The playlist should start playing.
Yikes. I hope that was of use.
