Thanks for such quick responses - I appreciate the help!
Prior to finding your site, I purchased a CD tutorial for PSE specifically for scraping. It was a tremendous help and really "jump started" my scraping. In this CD it suggested that you save 3 copies as I talked about above. I assumed 1 was for printing (merged or flattened), another for editing (layered) and another for web. Having now actually created some pages, I imagine I could save some space by simply saving it in layers (psd). I could merge or flatten prior to printing or uploading (keeping my project open) and print or upload to the web - then use my Undo history to get back to my layers and save that way before exiting the project or program.
Anyway thats why I've been saving 3 copies - I've only done 4 pages so far & I have to admit its alot of files to keep track of!
Thanks again!
