Here's a fun little feature. If you look at the top of posts....you will see a little scale...like a balance scale...that is a way to give some one "reputation" or just acknowledgement of a good post. A little box will pop up allowing you to approve or disapprove on someone's post although I don't really think we will go around "disapproving" things...lol. It also gives you a place to leave a little comment. When people "check their profile page etc they can look at reputation comments. As people gain reputation that little square box under the number of posts...turns green....and additional boxes are added as people get more "reputation"!!!
