What I usually do is go to the website of which you want to post the link.

Highlight the adress in the adress bar on top

right click your mouse and choose COPY.

Then go to NAT and write your post.

Choose the word you would like to be the link and highlight it.

Click on the little chain link in the reply window.

right click the first line and choose paste.

click insert

you're done
