LOL, cleanfan. Gave me a good laugh.
Back to topic... I would use it. It is always easy to invite people online. What's more, after the addition of the feature, you could add a point value per person you invite that actually becomes a contributing member.
For example, x amount of posts or an x amount of time by the new member will get the member who invited them x amount of points.
An alternative to points could be a shirt or something.
I would like to see a feature, after the new member gets their enrollment form to sign up for the site, saying "I was referred to this website by..." and have the option to choose "Existing member" then once that is selected, they should have the ability to input the members username. Then you can keep track of who refers whom.
Just a thought
