I have read on the dpreview forums about putting images on more than one agency as long as the images are not "exclusive rights".  I am wondering how to handle model and property releases.
As of now, I only work with Istock.  Their model and property release forms have their name on them.  Are there generic forms that all agencies will accept or must you get a signed release form for every agency you submit to???

Here I have included the release I use.

One important thing is that the release includes the models name and signature, and a witness name and signature.  The release must also include the ph #, address, and email of the release.  I have also put a place for the models picture, so that you can remember which release belongs to who if you have quite a few of them.

I hope this helps
I have saved the release as a pdf file.  I hope you are able to open it.

after running into problems with istock with not having enough info from my models, I have started to use the istock release.

However dreamstime doesn't like the istock releaes (because it says istock on it)  Everywhere else accepts it mind you.

What do you all do?  Is it acceptable to just crop out the istock info?
