I keep count sometimes. I ran a minecraft server for 23 months
   that I stopped back in Sept '14. Started it for my nephew when
   he was 7. When all was done, 27,000 unique people. I gave them a
   space to create their own world. I responded to problems with
   mean-girls, bullies, various forms of misconduct but mostly,
   just provided a safe space online. It was just for my nephew but
   it got pretty good. I saved the world - it's here on my HD - and
   someday I'll figure out a way to separate their creations and
   they can have them, if they find me (and I'm easy to find
   online) so they never lose the hard work they did.
