yes, what is this save as .tiff thing of which you speak?
I'm like you Brie - changing things scares me!! I print all of my LOs in batches and I'd hate to find out 30 LOs from now that I screwed something up!
I might need to change up what I'm doing though, as my computer is getting FULL...I think I need to just delete a bunch of older photos (they're already backed up). I just like knowing that everything I could possibly want is at my fingertips!
