Silly question

[koda2000]

What is the significance of the little truck pics under your forum name when you post? I have 3 orange trucks under my forum name. Some people have more or less than 3 and their trucks might be a different color (like black), or they may have none at all.

Example:
:exporange :exporange :exporange

I think it has something to do with how much of a post ***** you are.

Or some form of reputation points. Probably post ***** though seeing as I have 1 truck.
