On Fubar you have the option to LIKE people that you see pictures of. In order to like you simply hover your mouse over their picture on the shoutbox or the scrollers. You will see a green like button, simply click that button you will receive 220 points during happy hour for each LIKE.
Also if you have the NEW HOTNESS homepage style, you can LIKE from the users in the center of the homepage.
Fubar has introduced a DISLIKE button, this is a button just for fun. You don't get any points and the user is only notified that "someone" dislikes them and gives them a reason (such as point whore, asshat, and just cause) It does not say who DISLIKES them.
Then to RATE the user simply click the users photo yo go to the users page and on the left hand side, simply click on one of the cherries. the cherries are listed 1 - 11. simply click the numbered cherry you wish to rate that user.
