So there is a plot of land that I have seen on the world map that is fairly close to the edge but looks quite good to build on, assuming that there are no people who have laid claim to it, what exactly are the rules in coming close to the edge of the server borders? Are players not aloud to be within rendering distance of the edge or are they just not aloud to cross the edge?

Sorry if this is in the wrong area / question already answered I couldn't find an answer for this on the wiki/forum.

There are no rules. A Plugin is preventing Players to Cross the Edge line, its Porting you 10 Blocks back, when you Cross the line.

Oh thanks, I actually visited your melon farm and apartment and sent you a message in game. It was a great view, but sadly I missed the landing spot.
