Hi....I posted a few reviews a couiple of months ago to enjoy the priveliges of VIP membership.  Recently that membership expired(?).  I emailed for an explanation of how many and how often I need to post additional reviews in order to keep the membership up and got no response.  I have tons that I could write but prefer not to if I do not need to.  Does anyone know how many and how often I need to post in order to keep my VIP status?  Also, how long does a "review paid" membership last?

Thanks
