I started a couple new polls last night, and I set them stay open indefinitely (put a zero in the days until closing). Anyway, they both set to close in less than a week. Are we not allowed to make "open forever" polls anymore? Did I do something wrong? I definitely wanted these to stay open longer than a week since a lot of the time they're open will be a holiday weekend. I don't think I can change the ones I have open now, but what can I do next time to make this work?
