A week's not so bad since there's less then half a dozen that are any good. Whm legs, smn hands... I honestly can't think of anymore that aren't garbage.
I'll tell you this. Concidering SE of late, leaving the time limit was probably some crazy attempt to "keep people motivated." Much like the VW drop system. Now-a-days one of the hottest buzz words is storage and with dynamis so accessable now, who's going to hold onto all of the superfluous -1s while they wait? Innevitably leading to tossing the extras and thus having to return for them later. Hearsay granted, but plausible.
