Like trivia? I have been going to a web site called fun trivia for some time now. It's a great site. They have 2 hourly trivia contests going. Global trivia which is every 4 hours I believe. Plus tons of other trivia.They even keep tract of you stats.
Also you can belong to groups. I started one called the Mermbuts. Go check out the site. If you join let me know and you can join the Mermbuts. It's all free. No comitment or anything. If you join then stop playing, no big deal. It's all about having fun.
