Download the Tubepress plugin from [url removed, login to view] and add it to wordpress. The default code for showing a user's videos is
[tubepress mode='user', userValue='ParadoxBoxs']
I want to make it so i can get videos from multiple users like -
[tubepress mode='user', userValue='ParadoxBoxs,nanemtats,morphotk']
youtube does not have that API so what you would have to do is first get all the videos for each of the users and then sort and paginate them.
I will need to see a demo with admin login before i make any payments
