Keith .... I've been on this site for years. Although I have not commented much, I have learned a great deal from others including you. I'm pondering selling a portion of my royalties. I've received one offer which to me is extremely low. I would like to connect with someone who can give me an accurate value before I seriously consider any offers. I could peruse this site for hours, but thought with your extensive background in this field you may be able to pint me in the right direction.
