Ok, NOW what?
I've been submitting to iStock for a while now, and have several model images up. But now, I'm getting this rejection for EVERY model image I am putting up:

++This image uses a non-standard form of model release. Although we accept valid model releases that are not in iStockphoto's standard form, the model release attached with this photograph does not comply with iStockphoto's legal standards. In the future we recommend that you use the standard iStockphoto release.,

These releases are ALREADY on the site with other photos. These are not new releases.  I have model name, address, phone number, e-mail address, birthdate, AND a copy of their driver's license attached to the release. I also have photographer's signature, our company name, contact information, AND witness signature, printed witness name and date.
So, what am I missing??  Should I submit to Scout? Or just stop uploading people? It's quite discouraging, and I worry that if I make too big a fuss, they will pull ALL of my model images from the site, as I have been using the same release since the beginning. Anyone have a clue for me?

I'm interested in any feedback from any photographer that has worked with this company.
Thanks for your comments!

Anyone have some suggestions? We recently went to a Beach Boys concert, and got some really great shots of the band in action.  I figured out who all the band members are, from various websites and fan pages, and they are all ready for submission.
Question is... Which sites should we send them to?
Which sites seem to be good sellers for "celebrity" images?
Which sites just aren't interested in that kind of image?

Any suggestions or thoughts are appreciated   Thanks so much!
