What can it do?
Spawn+ allows your user to teleport to the "spawn".
Any special features?
If the player typed /spawn and if another entity / player is nearby it will say:
"Somebody is nearby stay still for 10 seconds!" after 10 seconds you will get teleported to the spawn.
If nobody is nearby you will instandly get teleported to the spawn.
/setspawn - set the spawnpoint for all players.
/spawn - teleport you to the spawnpoint.
Note: This plugin was made for a pvp server called chaincraft.org, but the Owner don't want it anymore so feel free to use it / decompile it.
