How come between 6 and 10 thousand posts you don't get flashing stars? If I had 6000 posts I'd want my stars to flash!
Also, is there any kind of sequence to the colours? To me the current system appears to be a bit random, whereas it could use a recognised sequence such as electrical resistor colours, or martial arts belt colours.
They were arranged like that in the star package I downloaded, I thought that they were in a reasonable order with the gold/bronze/silver colours near the end. The pinks in the middle are simply part of the colour spectrum that the stars go through.
