I am using aMember with vBulletin2 integration. I would like to offer new subscribers a 30 day free trail before billing them after that. However, I want to avoid having subscribers who signup for the trail and then cancel only to signup again and get the same trail. How can I offer the free trail only to first time subscribers?
