pgupta: regarding that little box that sometimes pops up, here is a portion of a message I received this morning from MyPoints:
"Thank you for writing MyPoints Member Care. As we strive to improve the MyPointsProgram the pop-up window that you see when you went to visit a site before will no longer be seen. We have decided to remove it so you can surf easier and more freely. Please visit the following link and read the important notice in the upper left corner:

I'm still not receiving all the miles I know I'm owed, but despite quite a few emails back and forth I'll just go for quantity and hope I'll be credited with 2/3 of what I'm owed.
