Titus enabled it. We didn't really know that we were getting it either, I'm not sure why some of the staff have it on and some have it off. I just checked and apparently mine is on, and I'm hot stuff

Really its just fluffy, kind of like pressing "like" on a facebook comment.  On other boards its called "karma".  I think its just another way to be more interactive on the board but it really means nothing. I'm sure it will be a bit of harmless (hopefully) fun and after we realize it really does nothing for the board it will be turned off...
