One of my articles will be having an embedded video in it. But when I go to the preview it only shows the embed code. How does it work for the articles? Does it show after submission? Or will it not work at all?

It will work when you have submitted it. For whatever reason, the preview seems to not always show the video properly. It should work just like if you were embedding a video here in the forums (using the <> Source Code) button to put it in there, then switching back). But do not worry. I will not approve it until it works. If it's not working when you submit it, I'll fix it in Admin.

Ok. I wasn't sure how it worked so thought I'd ask. Thank you

No problem TDitH.

Yeah I remember having a similar issue before. I finally just downloaded the video and uploaded it from my computer which worked. I've seen embedded videos from youtube before so I know it works.
