Was checking my cash back today and saw this announcement:
Jellyfish is Discontinuing the Refer A Friend Program
"Beginning January 4, 2008, Jellyfish will no longer accept new referrals under the Refer A Friend Program. We will continue to honor your existing valid referrals made prior to that date. Thanks for your support!"
It would have been nice if they sent an email about this. I don't think it's overloaded with FTer referrals though.
