Revamped Invite a Friend
The "Invite a Friend" feature at JewelryLessons.com has been revamped: now you earn userpoints which can be redeemed towards rewards each time you invite a friend. You get 2 points for every original invite and 4 points every time your invitees register to the site. It's a way to help the community to grow!
