Hello Alamy,
I see there is still confusion between contributors what RM-E means. Also on the guidelines there is not a right description.
Some of us think that this mean that the images can be only available on Alamy but been purchased by many buyers.
Others think that as soon some buyer purchase it the photo will be not available under that license anymore until the licensing time finished.
Maybe it is good to describe it on the guidelines, Forum or Blog so that it is clear for everybody.
Thanks.
Mirco
