I was wondering if it was possible to make open invites with rank restrictions. I made some open invites asking for players with a 1350+ rank to join but out of the 4 I made all the players who accepted had lower rankings. I would rather play people who want to play me instead of challenging similarly rated players. Great Website!
Go to "My Home", and scroll down to "My Challenge Settings". In there there is a section that reads:
"Accept challenges from players rated X to Y"
I don't know if this prevents players from outside the band you select accepting your open invites, but it might...
