I am afraid once you have put a stamp into your album there is no way for you to get it out. That makes sense, I mean you would only rip the stamp trying to get it off the paper wouldnt you :)

I've got more stamps in my album than I'm currently credited for in my High Scores. Why is that?

In order to update the number of stamps that you're credited with on your High Scores, you must first visit the Overview page. Once you've done that, the current number of stamps that are in your album should then be accurately reflected in your High Scores.

Okay, I've gone to the Overview page, and my Stamp Collection score still isn't showing up in my High Scores. Why not?

This is most likely because you have less than six stamps in your album. Once you have placed a minimum of six stamps in your album, your Stamp Collector total should begin showing up on your High Scores page.
