Jerry, paying members would still have the option to contact non-paying members. Saying they would be less likely to do so is purely speculation! If I was truly interested in a non-paying member, I would most certainly click on the option to "INVITE MEMBER TO SUBSCRIBE" and see what they decided to do. Is there anyone else who would do that????
I believe there is a very reasonable way to improve your site while still being straight-forward and honest. There are many successful businesses that operate by being staight-forward and honest AND listening to their customers!!!!
While you appear to be a relatively new member and may not be aware of the history, this is an oft-discussed topic and management has made it clear their decision was made with full awareness of members' opinions.
As always, you are welcome to make suggestion regarding the site via the Help system. I seen no reason to continue rehashing this in multiple locations in the forums, so I am locking this topic.
