My dear Jununger...
I think now is the time of change rating stars on members, because too much black colour everywhere in this site lately (and it getting worst day by day)!!!
Because I know that you'll start immediately stragling your brain to find objections, here's a plan of 8+ years for rating members:
1 - 30 Bronze level 1
31 - 60 Bronze level 2
61 - 100 Bronze level 3
101 - 160 Silver level 1
161 - 220 Silver level 2
221 - 300 Silver level 3
301 - 420 Gold level 1
421 - 540 Gold level 2
541 - 700 Gold level 3
701 - 1000 Platinum level 1
1001 - 1300 Platinum level 2
1301 - 1600 Platinum level 3
1601 - 2000 Diamond level 1
2001 - 2500 Diamond level 2
2501 - 3000 Diamond level 3
The round marks with bronze, silver, gold etc colours, instead of the white star inside them, they gonna have the numbers 1, 2 or 3 to indicate the levels.
After 3000, the level can be raised to 4, 5 etc or those members to be indicated as... stock holders!!!
