You just need to sign up for one of the free trials they offer and get
5
others to sign up through your link. Yes this is a pyramid scheme but
it seems legit as a number of people have recieved theirs already.

The important thing is to just remember to cancel whichever free trial
you sign up for sometime before it's over and it won't cost you a
dime.

Also you can now sign up for eBay for your referral, no credit card
required as long as you use a non-free email (i.e. no hotmail or
yahoo). Just join and bid on something, don't even have to win.
