The part that is always confusing:
An NMR is when a player doesn't sign into the game in question for a full turn.
They CAN sign into the site, just not visit the page of the game.
So, a player can log into the site, go to the page, do nothing (not read press, not enter orders, etc...) and not NMR.
Also, a player can log into the site, post on the forum, PM other players, but because they never visited the game page, CAN NMR.
