For those who didn't see, my kids are "kind of" big right now on the free, opensource version of Minecraft called Manic Digger. I do have a post in the general/main area, but they asked that I make a section on here for it as well..
They pretty much run the show - I do backend scripting etc (to prevent griefing etc), but most everything is in their court. Holla if you have questions/concerns I guess, lol
