Update: Frank, a blog commentator also added a $50 MSN AdCenter Coupon for Canadian residents. The above code only works for US residents. If you're from Canada, please use code: "SEARCHCA50".

only for new signups?

Honestly not sure, but the $5 activation fee makes it sure seem like it.

Thanks, been wanting to get back into MSN. Figured why not.

Yes, it is for new sign-ups only but still a benefit to some (multiple cc). cheers.
