Okay I'll try again.
There are 3 levels of functonality I'd like for this hack:
1.
a)Take a users's reputation rating and divide it by their post count and put it into a variable somewhere.
b)Trim this figure to just 2 decimal places and display it in the user CP somewhere
c) Display this figure in the postbit underneath a user's name.
2.
a)Display this reputation ratio value on the memberlist.php list in an additional collum
b)Allow the member list to be arranged by reputation ratio
3.
a) When displaying the memberlist by reputation ratio, ignore users with less than 50 (or "X") posts, so as to omit low post count users with dispropotionate reputation ratios.
Anyone who's at all interested in doing this, please make from 1 through to 3 in that order, cause that's in order or how important the steps are
