Sometimes the Yahoo Suicide Lounge you want to play in is full. Life is full of tragedy, I know.
Don’t let the fire marshal keep you out, use a back door!
There are a variety of sites which provide back doors to Yahoo game rooms. I believe you have to be already logged into Yahoo, but I am not 100% certain of that and it may vary by site.
Currently I use Shove-It which works quite well and does not have pop-ups.
