It can take some time to get into recruiting. Some people find it easy, others - like myself who have no practical selling skills find it a little more difficult.
For me I Joined in August 2010, I got 3 people to join (family members and a friend) in the 1st month making a total of 8 (£40) for my 1st payback amount in December 2010.
It took me around 6 months and quite a bit of good luck before I got the hang of it.
Almost all of my recruits (90% +) have come from online Activity (eBay, Twitter, and giffgaff community)
