Thanks so much for the feedback. I'm asking the developers about automatically removing blank waves. That seems like a big win. Otherwise we might have to have it as an option under "report" and rely on the community (at least initially) to mark a blank wave as blank.

As for the language barrier. Yes, we're going to be english only to begin with, then I think we'll make versions for other languages.

I'm trying to think of the best way to simply message this right now. Let me know if you have any great ideas.
