Yes, Valentino, I've been selling Rights Managed licensing since 1995 and have been waiting years for a platform to sell my images like this. Doing well with it.
Kathleen, if you're not comfortable with the RF licensing don't do it. Personally, I think you're a smart lady. Learn more about that first before to dip your toes in it.
Also, if you have images with people and don't have a release, you can uncheck the commercial rights and just leave the editorial rights. RM that is.
