Selling Cards
F Share - Facebook Share
There is a little "F Share" icon under each of your cards in on a Card Details page as well as provided in your email notice when you sell a card as shown below. By clicking this icon the card thumbnail and a link will be posted on your Facebook wall if you have one.
Artists have found this to be a fantastic way to share the news of your sales which encourages your Facebook friends to check out your card and perhaps buy a copy in the process.
