Hey guys,
I manage the wiki and I can say that we have gotten quite a few nice tutorials from the community even only a few months after launch:
https://wiki.unrealengine/Category:Tutorials
https://wiki.unrealengine/Category:Code
Additionally, we have begun transcribing some of the videos into text and I am considering adding that text to the wiki for referencing. If there are specific tutorials you would like to see in text, please let me know and I’ll see what can be done.
