Contributor list
In the same way that a donator list is presented, I think it would be a good idea to have a contributors list as well.
When a donator list is presented, it incentivizes people to donate to show that they support the site. The same happens with the statistics board, as users can show off their knowledge and dedication to running the site.
A contributors list would be able to display those who actively want to improve the DefendTheWeb project.
Also, I'm pretty sure when DefendTheWeb was HackThis!! we also had a page for those who found exploits in the site. That may another feature we consider adding!
