I understand the only benefit you are getting for your extra dollars is the ability to access semi private pictures and the videos. Getting access to pics upon request, the buddy list, who saw my profile, communicating with other members, these all are features available for free. Just sign up for the free membership.
I paid many times for the premium level, but I do not think I was getting enough in exchange of my dollars. Actually, the reason why I was paying was the assumption that being a premium member would give me more weight as a prospect hirer.
