should be "by invitation only" to keep it exclusive. ask every new member to invite only the three coolest friends he has. Everybody getting an invite will use it, just not to lose this chance (invitations only valid for three days or so, decide now!)

(do I get free membership for this great idea?)

Also may I suggest restricting early members to only those with @Harvard.edu email addresses?

I toyed with the idea you can only pay to get somebody else into the Club, and you can't pay if you're already in the club. Mostly just because I thought that would generate some funny dynamics.

I think the invitations idea is a good one, though I want to keep it so every member has paid $1 to get in. maybe adding some incentive to getting your friends to join. Like your name appears in a slightly larger font if all three of your invites were used.

Right now it's just a static HTML page that I'm manually updating, but there are a lot of ideas, like this one, I'm hoping to play with.
