Below is a copy of hwo they say to embed from the plugin, and it speake of putting the destination into the slug url in the editor. Not there! Canany one help with this.
Thankyou

Let’s start by assuming you inserted “trailer” as your Embedded link. Now you need to create a page on your blog to host the trailer.

? Write Page
– Under your WP admin panel, go to Write ? Write Page.
– Title this page whatever you like. “Movie Trailers” works…

? Post
– Feel free to write whatever you like in this post.
(Or don’t write anything at all)
– When done adding content, it’s time to add the TA embed code.

? Code
– After done adding content to the page, click the Code tab.
– Wherever you want the trailer, all you have to do is paste:
<!–TrailerAddict–>

? Slug This Last Step
– Remember your Embedded link? Click the Page Slug.
– It’s located on the right, above Page Author… Dummy
– Write your selected Embedded link into the Page Slug.
Save the page and All Done! Give it a try!
