I know that the server is reseting soon and that all players will lose their houses items etc.

What if you didn't have to though?
So I have a suggestion, hear me out On the last day of v5 give every [member] and above world edit  they can use it to select their house and save it as a schematic.

See the way schematics work is that they are saved to a server not to a world when used as a plugin.

I realize that much power can be used wrongly so make it a fairly short time frame say around 15-25 minutes

as for v6 placement of these schematics before even getting the ability to world edit. members must sign a form that says that they will not grief or they will be banned..

Sorry to tell you, but this will never happen. World edit is too great a power for players to have the ability to use. I guarantee it would be used wrongly during its time active, even if it was for a very short time. Also, this would never happen because it would be unfair to players who couldn't be on at that exact time. Anyways, the world reset is meant to be a RESET, not a transfer. If you want to build a replica of your house, that's fine... Many people do. However, your houses will not be transfered over into the new world.

Took the words right out of my mouth...
