Last night, my STL, who was closing LOD, had a post-closing huddle to let us closing TMs know about some of the changes coming up. Apparently, they're gonna score each store by the number of REDCards they get each week and have a threshold they need to meet every day, week, and/or month to get a good score (so if your store gets a lot more REDCards than predicted on one day, the rest of the week won't be as tough, and vise versa). He said that starting Sunday (Feb 1), there won't be anymore prompts about trying to sign people up for the REDCards either, so I assume that some (if not all) of the changes will start around that time.
Edit: The stickied AE2015 thread seems to be the main place to talk about this as well as the other changes coming this year. So, I'm thinking this might get merged with that and/or the main REDCard thread in I'm Lost!
