Tengaged should have a feature similar to Facebook where you can request that someone be your friend and they can confirm or deny the request. That way all of the friendships would be mutual instead of some people adding others as friends and they don't even know about it.
I won 1st place in only my 3rd castings game since I joined tengaged a week ago! :D I can't believe how lucky I was in that game - I found 6 keys!!! Also, my best friend got 2nd place because of his amazing challenge scores! I'm so excited and can't wait to buy the various colors so I can play all of the different games (especially Survivor)!!
