The other day we got the Youtube extension implemented on the Wiki.
If you have a video tutorial on Youtube about UE4, please come to the wiki and make a page for it. Fill it up with all of the information and updates you want to keep it up-to-date. Then add this to the page: [Category:Community Videos]]](Category:Community Videos) and it will show up in the video category.
You will notice there are two sections on the wiki for videos; Community Videos is for all the videos that you and the community make. The other category, Epic Video Playlists, contains links to the playlists that we have provided on Youtube already, but with additional information and links to the documentation.
Let me know if you have any questions!
