TL;DR: COLORS!!!
On Sapphire's suggestion and with Kraco's help on making some new colorful boxes, I've implemented a change to the rep display system. Now it fills bars, then replaces them with the next higher value ones. From lowest to highest, the colors are:
dark green
light green
dark blue
light blue
purple
Also, heads-up, sometime tonight I'll be knocking the forums down for a couple minutes to upgrade vbulletin again. Should be minor, already tested it out in a dev instance, but probably 15 minutes or so.
We now return you to your regularly scheduled forum activities...
