From HoNwiki

This page lists every thing that needs to be done on the wiki and how you can do it. There will be a courier next to the topic if there is a way to earn a forum award by doing it. Every thing else is general stuff that needs to get done but if you chug through a giant pile of general stuff I will probably toss you a forum award as well. If you think you deserve a forum award for any reason pm Drasha on the forums with the reason you should get the award and I will look into it.

Hero Pages

Adding 3 hero pages to the wiki will earn you a forum award. You can learn more about how to do this on the Hero Page.

Mechanics

Just adding 3 mechanics pages will get this award here.
