not quite a pet peeve but I don't get the point of having reserves and app challenges.

doesn't allowing app challenges negate the point of reserving at all? it's just a notification for the mods that X is going to app Y. which is fine but it's not a reserve and they should use a different word.

it's like saying you can buy a ticket for a play only you might have to prove to the ticketmaster that you're more worthy to attend than this other person who wants that seat.
