I don't know if it works, but I thought it would be a nice thing to have if it would.
After Credits, in your description, there could be a "rep status"
This would give you a rank, on how helpful you are, determined by your rep. It could be as follows:
Under 0: Noob L33cher
0-5: Possible Scammer
6-9: Possible Helper
10-24: Helping out
25-49: Rep is Building
50-99: Helpful
100-199: Highly Trustable
200-299: Safe for Trade/dl [Not sure what to put for this one]
300+: [I don't know]
The reason for separating 1-9 into 2: people might be insulted in being called a scammer.
I don't know exactly what names should be, you may want to change, becuase some of mine were not creative

Just an Idea
