Well, I can't take all the credit for this. Let's thank elucid for the idea.

NOTE: The point system takes effect tomorrow(since the new task will be assigned).

HOW IT WORKS:
Each week there will be some competition to earn points, or lose them. In order to get points, do the weekly task. You lose points for not doing the weekly task. Everyone starts at 0. Your points CANNOT go below 0(this makes it a little more fair).


HOW POINTS ARE DISTRIBUTED(AND LOST):
As said earlier, you have to do the weekly task to get points. Not doing the task, or failing it results in loss of points.
Everyone starts with 0 points. Your points don't go any lower than zero(to be fair). Well, the redundancy is over. Here's a nonredundant piece of info.

POINTS:
Completing the task:
Thursday=70 Points
Friday=60 Points
Saturday=50 Points
Sunday=40 Points
Monday=30 Points
Tuesday=20 Points
Wednesday=10 Points

INCOMPLETETION/FAILURE:
Incompletetion=-10 Points
Failure 1:-5 Points
Failure 2=-10 Points
Failure 3=-20 Points
Failure 4=-40 Points
Failure 5=Loss Of All Points(I don't see how you could fail this many times)

You can only fail five times a week. And if you manage to get any points and fail five times, you lose points for that week(the week before if none were earned the current week).
