1ninjadude1701, your challenge is unapproved because you're not participating. Also, this is too similar to a speed run, but with a time restriction. If you're going to make a speed run type of challenge, it would be better to just leave the time open to the player, since 7 hours is...a strange time.
-ty-, your challenge is unapproved because I already plan on remaking that one as stated here:

It will be back in November, after the event this month. :) Plus, like I said in that post, I don't appreciate my post copied word for word. And putting it with the least favorites challenge seems a bit two confusing. Feel free to restart the least fave challenge as its own thread if you'd like though, since I have no plans to bring it back lol.
