You get the .schematic file go to the search bar and do %appdata% > .minecraft > config > worldedit > schematics. Once the schematic in there ingame do /schem load schematic [schematic name]
If you wanted to export use worldedit to select what you want to export and do /schem save [ name]
If they join and automatically join at a certain spot you can put a command block with a pressure plate on it and surround it with barriers so they can't move off it and have the command with the block be tp @p x y z coords
If your using essentials protect and antibuild. I recommend just deleting them and using worldguard. They just cause more problems than are worth. but if you do stick with them make sure you give them essentials.build.*
Essentials works for all for all for those plugins. https://ci.drtshock.net/job/essentialsx/ Just don't download the ones the ones you don't want. Essentials also had a config dedicated to each section and I know you can change how everyone's names look.
Just tried it out on a server with essentials, Worldedit and Pex and I had no trouble. Could it possibly be another problem with a plugin? if you don't mind listing them I can try again
There is a plugin that uses /rlt go to teleport people on a server i play on thats 1.8.9. Idk what its called but you can probably find it with some research
