A person I spoke to once on BGA alerted me to this site. He said that I could do auto-match with "wait for expansions" checked and get a match within a couple minutes. I have tried this a few nights, and never gotten a game offer. Names appear and disappear from the queue, but nothing happens. I see another post says (after hitting the 'i'):
(this is only visible if you have 'advanced' checked and are currently searching)
This box gives you a bit of feedback about the other searching users, and tries to explain to you why you're not in a match with any of those players. If you click on the name of another player, the colors of the searching options will change to reflect this. Green means there is no problem with this option. Red indicates there is a problem you can't solve (but the other player can). Yellow implies there is a problem which you could solve by relaxing your search criteria.
I don't see a box to check that says 'advanced', and clicking on people's names does nothing. Would love to get into this site and try it with expansions before deciding to get a membership.
