Pls let me know how I could add my videos to the movie gallery?

Looking at the movies in the gallery, thay all say “Published by: The Area”. So I’m guessing that a senior admin is hand picking movies to go in the gallery, rather than a free-for-all where any members can add their movies.
You can make your own portfolio here, or use the Highlight Your Work forum to add your own thread and use the YouTube link function to add your movies.
