Since last Friday many comments posted to The Intersection are landing in our spam folder. Unfortunately, once there they are quickly buried under a mountain of repetitive ads and offers. We are currently looking into this issue with Discover and appreciate your patience as we work to identify the problem. If you don't see your comment posted in a reasonable amount of time, send an email and I will search for it. Thanks for reading and participating, SK
