Well...the big issue for me is people who continually post confirmed, and keep backing out. I've noticed it's becoming a trend more and more - someone should probably start taking notes.
Just to be clear, it's quite understandable that things come up in life. Your ride fell through, your gun broke, your daughter's sick, etc... However, the simple fact is that you posted that you were confirmed for the game, and you're counted on to show. Not doing so, as people have previously stated, causes certain problems for many people.
If you bail out at the last second on a game or two - it's no big deal, shit happens. Just PM the host and explain and I'm sure it won't be a problem. It's when it becomes a habit that it becomes a serious problem. If you're not sure if you can make it or not, post a tenative. If the host only wants confirmed - then don't post at all or PM the host. Seriously, it's not a hard concept folks.
Personally, I'd prefer public tabs on how many games people have bailed on. If someone's confirmed for 15 games and bailed on 1...understandable...if another person confirms for 10 and bails on 6...you get the point.
