I am starting to be a more active member of the community recently.  Shame on me for taking so long to do so.  I have been using models from here for years.  I may just be uninformed about the site, but I've noticed some things that seem strange to me, since I started entering images in the facebook competition.  The first thing I noticed is that your "raters" go away sometimes.  You have someone rate your image and they continue to show up under "your uploads", but from the main [sorted by ranking] list, you lose their rating after a day or so.  Does anyone know why this happens?  I also looked to see who some of the people following me were.  When I saw their images and models, I wanted to follow them too.  Now in the listing of images under ART, they are gone as a follower.  Yet another mystery to me.
