did you try going into gallery at the top of this page, then scroll down until you find a gallery for scrapbook pages, click on it, then look for the 6x6 section.
you can put SUO or SUM into the search in that gallery, that will take you to SU only or SUmostly creations, the only trouble with that is it only shows the pages that someone tagged with SUO or SUM so you don't see all
this is the 6x6 page gallery link, i didn't limit it to SUO
