How to make clickable links now?

I noticed among the many changes I can no longer create clickable link the way I knew how. 

I would like to list my horses for sale with more detail and a link but can't figure out how.

 Is their a new guide for this??

If you click the little link icon way to the right when you're making a post, it'll pop up a little box where you can add a link in. You just paste the url in the box, and add any text if you want the link to show as words and not just a plain link. The shortcut for adding horses no longer works, as the BBCode format was updated, so you'll have to add horse links as normal links for now.
