I just now sent off an email to USPS to delete my photos and close my account.   I couldn't find anyway to delete the photos myself.  I'd really like to have that option but it seems it can't be done.
         After reading all the problems above, it is going to be interesting to see how long it takes to complete this process.
         I find it interesting that the top sellers at USPS with 'folios a few thousand strong, and with 1 and 2  hundred thousand views...  have only sold  170-200 times.  I do well over that every month on SS with a folio only a couple hundred strong.   With  only 6 USPS downloads in 10 months.. I think it's time for me to move on.
    For any others thinking of bailing out of USPS... I'll keep you informed. 
.........although, I don't recall seeing any MSG names on USPS lately...

              am i the last???    -tom

I emailed support and they did it.
