Ok, found it - any portals within 1024 blocks (in x/z dimensions) will link to the same nether portal (because Nether is 1/8th the size, and a portal has a "range" of 128 blocks within which it connects, and 8*128 is 1024.
Oooh... interesting... but that's guns and grenades, and has two teams, and you can't dig below sea level, and there's only one type of block, and there's no crafting, doors, lava, animals, or redstone. Worst of all though, it's got a fucking shit name. :@
If you go to minecraft's website and play it in the browser and tell it to connect to the teh server is it really connecting? I did it but it doesn't look like the real teh world to me.
