@camcallahan Sorry about that. Can you send an email to firstname.lastname@example.org with your domain details?
@DeafThunder You will need to go to YouTube and click where it says "embed" for your video. You need to copy the code there. Then in Known under Post, click the link to "switch to plain text editor" and paste your embed code for the video there. That's how you embed media from services like YouTube, Vimeo, SoundCloud, etc. Does that help?
