The page jumps around even when you are signed up and only have to click in. Besides being badly written code for displaying the page, I think what is happening is that the site us checking for new offers and updates in a particularly clumsy manner. It is a surprisingly clunky commercial website.

I'm not sure. I know prior to the change I was getting a lot of emails announcing they were updating the program with new rewards, etc. it seems like they either upped the points on my favorite rewards and/or put more restrictions on point submissions. "Update" seemed to actually mean "downgrade" the program.

I'm not really sure. Sorry I couldn't help. I have only hear about coke rewards through McDonalds and I didn't see the old site.
