Would it be possible to announce the exact moment the Nether and Miningworld are being reset ?
Perhaps a countdown timer, or Calendar widget on the main page ?
I myself am always worried around the time that people claim that Nether has reset.
I use a /home command to get to Nether and am worried I might end up somewhere nasty after a reset.
Knowing that it has reset, or when it will be reset , will persuade me to use the normal portal that day.
