How about some badges which staff members can vote on a monthly basis for the 'best' reporter. Could encourage users to report more, and include more detail, and tackle more complex issues.
Why not just go with the same coin theme as the existing rank icons, but in a different color that indicates a white-hat look & feel, such as green? All of these ideas are great, but most of the suggested icons do not fit the current look and feel of what the forums have to offer.
Sometimes the most subtle changes/additions are the most effective ones. Thoughts?
It doesn't stand out enough for me to encourage users to report more. I think making it unique to the current ranking up ones would be better, and more effective in getting more users to report.
