When you search for Calendar in the photos section...NOTE that new photos could be ANYWHERE in the mix. They don't necessarily show up on the first page...so if/when you have time...flip through as many pages as you can. It's a LOT I know...eeeek! But at least vote for your favorites.
And you can only vote ONCE for any photo--it won't let you vote more than once. If you change your mind and want to re-rate a photo higher or lower--that new rating replaces the previous rating you gave the photo.
