"Expired Ad" stamp (like a "Sold" stamp, but for "Expired" ads)
Some forum members have shared tutorials on how to create a "Sold" stamp and a "Sale Pending" stamp; for example, a red rectangle that says "sold" (or "sale pending") next to the ad title or thumbnail image.
I want to create an "Expired" stamp, to show visitors an ad has expired.
Have any of you done this, and/or have any tips for implementing it?
