NeoWikis are all about community effort, as well as recognizing those who contribute towards the knowledge base.
Towards this end we have several things that show who is helping out:
 History list
Each page has a history, showing a list of all contributors to the wiki.
 Last edited by
The last person to edit the page is credited in the bottom of the page.
 Last 5 contributors
The avatars of the last 5 unique contributors to a page are shown.
 Major portions written by...
This new feature will "permanently" credit authors who wrote large chunks of the page. You can see this feature in action in the below screenshot.
