Just in case you’re not sure how to do it, here you go! (click on the pics below to make them larger)

While you are writing a new post, click on the yellow button (in the tool bar) with a “v”

Make sure you have copied the link of your video from the youtube website, the link you need is found to the right of the video box. Copy the one that says URL

Then simply paste that URL code into the box that pops up when you press the yellow “v” button

Publish your entry and your video will show up in your blog! Have fun!
