Steam Text Format - Guides

I think you can just post the link. It happens when I post a Gallery link or Greenlight link.

For other links, [url=link]text[/url]

[url=http://blablabla]your text[/url]

Cant be that way. That way only does a hyperlink to youtube
I need like is one the image, it show a little resume about the youtube video (pick up the description on the video)
