When viewing Everybody’s challenges you can click the From/To button at the top. It first sorts the list by From,A-Z and clicking a second time sorts it by From, Z-A. When you’re only looking at posted and you click From/To it just randomly sorts it as far as I can tell. Would it be too much trouble to have it sort by To,A-Z / To,Z-A when looking at posted challenges? Not a big deal but it’s basically a dead button that could still be really useful.
