Yeah, Neko, from this news post: "For the first few days, an additional new task will appear each day for a total of 8 different tasks." :) I also miss the leaderboard. XD
That's pretty neat about the overtime rewards. :o
Also:
"Your current tier is SILVER TIER.
You've accumulated 10315 points."
So yeah, I just misunderstood the 10 minute update thing... because I thought it upgraded to Bronze instantly, so I figured it'd upgrade to Silver instantly. But I guess it just was closer to the 10 minute mark when it upgraded to Bronze. >.>
