I have amended the credit calculations for the fanfics forum to:
  • The Fanfics forum HAS a Post Size Credit of 0.025 as opposed to the default 0.1.
Basically, this would mean you only get one quarter of the credits now for post size. As time goes on, I'm sure we can better refine the calculations used.

I have updated the FAQ to reflect this. Please see the last point. Credit Calculations.
