From Diablo Wiki
You don't correct the info in the boilerplate, you correct it on the wiki page! Silly rabbit... -_-'
multiplayer= Can you play this mod in multiplayer? Yes/No.
What exactly does this mean? As far as D2 goes, the only way to disable multiplayer is by editing the code, and (assuming you're talking about TCP/IP) I don't know of any mod that does that.
download= Download url.
Link to a mirror page, good enough?
