I'm not talking about the images of elite, mods, admins and all those things. But about those little gray blocks ((for normal members)) Starting from 1000 posts I think, non will be added. Adding more will clutter it a bit, so what about a bit darker shade.
Like let's say 0 is normal and the 1 is a little darker shade.
Now:
0000000
Later if you have let's say 1500 posts
1110000
Small idea. I think that would be quite nice, and not that difficult to do.
