I don't think you're going to need these gimmicks to get signups Audrey
Though, you could try a few things:
- Calendar, Mug, or Pens etc.
- Personal letter to all members who join - lipstick kiss on each one
- Have a video a week for download, (not live) that's set up for a particular fetish - pantyhose one week, then a dildo set, then something else...
