Your Monday morning mission, should you choose to accept it: sign-on to help our staff writer, Jan Birkeland, win $US1 million.

It works like this: home-grown social networking site iYomu.com wants to attract millions of users worldwide. Its weapon of choice in the publicity war is a $US1 million prize to be paid out in the new year. To be in the running, you have to sign up to iYomu.com, and solve 10 onscreen puzzles, getting more points for each puzzle you solve. Beyond that - which Jan and others have already achieved, levelling the playing field - you get points for referring other users. Everyone who's on the site's top 10 leader board on Dec 31 will then be in to win the $US1 million, to be decided by a popular vote by iYomu members.

Now, iYomu wants to attract as many as 10 million users by Christmas. However, from what we can gather, things are still a little quiet. So, I figured, to help iYomu gain some more members, and struggling young house owner Jan to win $US1 million, we would start a concerted pcworld.co.nz campaign to get our staff writer onto the site's leader board.

Jan reckons he needs to sign-up about 80 referrals to get to the top. If you want to partake, then send your email address to jan@pcworld.co.nz, and Jan will send you a referal email.
