While the old method is still working, nobody ever mastered it. So here’s a new way to post videos which should work from any site.
1. open Jewtube and locate the video
2. click on the text field next to EMBED (you can make adjustments in size and colour or leave it as it is)
3. copy the code in the text field
4. paste it here

Code should look like this:
5. Hit “preview” to adore your awesome video, good work!
