I was getting invalid links and I emailed Motherwear for answers. I just received this email:
"Our account is currently inactive and we are looking to move the program elsewhere or house the program internally. Unfortunately, the account became inactive before I could communicate it to our publishers so I am glad you emailed. Any commissions that are pending payment will of course be paid out and I will keep your information on file for when we kick up our affiliate program again."
The email goes on to say that they will be in touch with me later this month.
Major bummer. Time to pull links. MW links are working ... but no commissions.
