As for idisk. Hopefully some sort of solution emerges from Apple.
Me too. I tried SS and left after 4 mo- I did not have full control over my folders and albums as PDF files are considered images by them and even after users delete folders, the orphaned album files remain veiwable and can only be deleted by SS tech support. I didn't appreciate that SS forced PDF docs with personal info to be viewable as images in albums.
I hope DB improves to allow non account holders to access folders by URL and password but not holding my breath- still looking. Hope some company will mirror the SmugMug concept with PDF docs. Perhaps Google Docs has made some advances in that area since last I checked.
Thankfully I had MM last summer when I closed a mortgage and had 30+ PDF files in an iDisk folder for the bank, underwriter, title and closing agent to access. It would have been a nightmare to email all those individual signed files or file links.
