Hi,
I've never used the Elements Organizer, I'm afraid. Many years ago, when I used a PC, and was using an early version of Elements, the Organizer (kind of without my knowledge or intervention) "took over" and started "importing" my photos into its library. I had no idea what it was doing, and since I had thousands of photos spanning many years, was aghast at this intrusion. I stopped it, and could not make one iota of sense out of what it did or why. There didn't seem to be any semblance of intuition in what it did. I consider myself a reasonably intelligent person, and reasonably savvy with a computer (be it a PC or Mac) but was dumbfounded, mystified and befuddled at what it did. Since that time, because this was so invasive, I have sworn off any kind of photo organizer because nobody can organize my own photos better than myself.
Since that time, I adhere to a simple, easy to understand system. Under the Photos or My Photos folder, I have years; and under each year another subfolder by date, or weekend or event or month, depending on what I've taken. Sometimes I violate this simple system, for example under "2012" I'll have "2012 Lacrosse Season" and under that will have folders for each game. Therefore, the entire subject of my child's sport season is in one folder. It doesn't matter where the photos come from--iPhone or camera, they end up properly nested.
Periodically I'll rename some photos that are very good, or ones that I use for enlargement, sending somewhere, etc. In that case the photo then will have a name besides DSC0001 or IMG0987 or whatever the camera or phone assigns.
Admittedly this is low-tech, and I should go through the Organizer one day and see if it works better, but my system works for me.
