mycokerewards.com failure

Oops - Lost connection to MyCokeRewards - the only response I am now getting when attempting to enter codes (after a one minute wait per attempt). And how about setting something up so we can enter multiple codes at once? Having to click on a submit button for every code even though multiple codes can be entered on the page is NO different than using the default entry box on the home page. Let me key in one code per line in a multi-line text box and hit ONE submit button ONE time to enter them all. Anything else is just wasting my time.
