How do I create a link where it generates a preview of the webpage in my post?

I can only seem to create hyperlinks.

It happens automatically, but only with certain sites.

I just went to the link you posted.

Then I copied the url from the url bar, and pasted it directly into my post.

The forum software does the rest.

Sometimes try indenting it with an “enter” before or/and after the link
