I signed up with www.xoom.com today and checked out their site. It is virtually identical to Mypoints and you earn points exactly the same way. Curiously there does not seem to be a prohibition from joining both programs.

Unfortunately you can't redeem your points for Vacationmiles but you can redeem them for Alaskan miles.

Looks like even more reason for a board devoted to such free point scoring opportunities.
