I use to belong to a drumming forum that had gotten huge. New posts were written about every other secound on the bussy times. There everybody had rep bars up to the max and it wasn't hard to to because the forum was so big. I'm pretty sure that's why nobody has that much rep... it is still a rather small community (which has good potential though.)
The Downfall to this was everybody wanted rep... thus began the "Rep *****." People who would beg and beg to be give rep... post random posts like "I need rep.. give me rep" or "rep for rep" It began to get annoying after a while. I was kind of glad that this forum didn't have that issue.
btw... can't the administrator allow for one to see who repped them? when this was introduced on the previously mentioned random neg repping when down completly.
