MCrow
What I meant by “ add a command for selldoor to update a door..” was for the below.. aka when you buy a door, it already gives a date, then use /updatedoor to update the door date.. or have it update when a player joins.
Basically, the reason I made this suggestion was for more servers that would opt for a date to be shown on a player door that have player decay disabled.. if enabled, this would also be much easier than having to look at a log of when a player last joined instead of looking at a 1470.
