So I haven't logged in for quite some time, but I can't seem to join any games through the Waiting Room.  I found several games where I am within 100 rating, so I'm not sure what I am overlooking.  Anyone ever experienced this?  I seem to be able to register new games without issue.  My apologies for the “noob” question, and thanks in advance for the help.

I figured it out.. I swear the last time I played you had to join games instead of just being matched. Mods can remove this thread if needed.
