Look in /etc. There should be a file mpd.conf. That's what MPD uses if it can't find anything in your local directory. If you want to set it up for your own identityr, just copy /etc/mpd.conf to ~/.mpd.conf ( or something like that, look through the rest of this thread) or just create a new file. Then, when MPD starts, it'll look for that file first and use it instead of the one in /etc. If you want to have different configurations depending on who's llgged in, you can, y creating different firesl for each person and saving them in their home directory.
