Getting SMP maps?

How do I get someone else's SMP map..

So I can *cough* x-ray it

You want somebody's singleplayer map?If soo u need his 'world 'x'' file [x is a number 1-5] And then u just paste it in ur save games and thats it

SMP is Multiplayer map... and you would have to have a client much like WoM to be able to do that

You cant go Alpha on that ;/
