Here is the Nether Render: It is the exact same dimensions as the Over World
That helps like NOT AT ALL LOL
One thing about Portals and Players not of the FG membership:
I disabled the ability to make new portals, I also disabled the End. There are several reasons for this, the first of which is both of these maps are just over a gb in size, so the servers static playing area is roughly 2.3gb, thats huge. Every portal adds in another point to manage and for resources to go to. So limiting them, and keeping a set portal at spawn is a good way to manage it.
That said, I am upping the # of warp points people can have. Also, I plan on researching today how to make the amount of land claims everyone can have based on which world they are in. This will also help you guys get back and forth, and keep the server running cleaner.
Lastly, with the "Random" placement of portals in the Nether, I dont want to deal with peoples builds or towns overlapping, or trying to manage that by "moving" portals and then linking them (Seriously, its a HUGE PITA)
