The wifi at my university is pretty terrible. However, my professor insists on using poll everywhere for quizzes everyday. Often, I miss a poll question simply because my computer or my phone cannot connect to the internet. I can't send via text because I don't have service. It would be nice if I could send the poll whenever I got wifi. Of course, this will may require a complete rewrite of your backend because a poll completely closes when the instructor decides to. And the code doesn't work afterwards. But maybe if the time the response was cached is before the time the poll closed the user could still get in.

Just an idea. I know a good number of people who this applies to, but I guess it's a relatively small percentage so it may be too expensive to construct.

Thanks
