If your new and dont know how OPEN Games work, here is a run down.
If you see an OPEN Game on your schedule it means that an inactive Member has been removed. You are noe free to play any one in either league (EAST or WEST) with an OPEN Game on their schedule. There is no restriction here however in order to get credit after you play WIN or LOSE. You must both tweet the score to @MRLSCORES with this format below.
WINNING TEAM:
@NITKA32 EAST beat @GOLDENRAGE WEST 45-10 in an OPEN Game.
LOSING TEAM:
@GOLDENRAGE West lost to @NITKA32 East 45-10 in an OPEN Game
