iDine/Rewards Network - Welcome bonus link in United email - works of existing MP dining!

There is the link at the bottom of my United email:
You're enrolled. Earn 1,000 miles with your first meal. (http://link.p0.com/u.d?QYGhbReA7hSrDX8Ign1RZ=5311)

So I clicked on it (being already logged in into MP dining) and it allowed me to register to the bonus: "Earn 1,000 bonus award miles for creating an online profile. Exclusively for MileagePlus Visa CardMembers"

It registered for the MP account with and without Visa.
Of course YMMV

Thanks for the tip...same thing with me. It shows me as registered. We will see if I get the miles. I have had the account for some time so I was surprised I could register...
