Ex:
if(gameversion != hubversion)
alert("The server's build is an old one, you should update!")
gameversion = In-Game variable that is changed in the Code
hubversion = The variaible in the HUB Edit-Page (one of the last things has "Version")
This would be helpful for if I have more than 1 person hosting for me. I can get them to update without having to tell every host.
