XF 1.5 Automatically changing a pasted link to create the title


Active member
i have two sites running xenforo. On one, when I paste a link, it automatically changes the hurl test to the title of the article. On the other site, this doesn't happen.

I vaguely remember clicking onto something in the ACP to set this up for the one site, but can't remember how I did this.

Is this a xenforo feature, or an add-on? Any idea how I can set this up on my other site?

Thank you
