I went to MyPoints to link to icollector at https://register.icollector.com/mp_promo_full.html
and got a form to join but I had to provide my CC number, I don't like these kind of promos. However the link provided by UserMark https://register.icollector.com/mp_promo_quick.html
does not require much info (name and e-mail) but only gives 100 pts rather than 180. I chose the quick one.
