Fans are a fun way for you to follow other members on Listia with the same interests! When you become a fan of another member you will be able to see their newly listed items in your "My Listia" page. There is a limit on the total number of members you can fan at any given time. You are allowed to become a fan of 1000 members, but after that the ratio of your fans to members you fan has to be greater than 90%. If you do not meet this requirement you will not be able to fan any more members until you increase your ratio.
You can fan a member directly from one of their listings, by clicking on the “Become a fan” link directly underneath their username, or by clicking the “Become a fan” button on any member's profile page.
To un-fan a member, click on Undo.
