Links in SDN forum posts

Hello!

This is probably trivial for most of you, but I just can't do it.

How do I create a link in a SDN forum post? The standard way doesn't work, and tips from the weblog "Weblog formatting tips&tricks" by Mark Finnern obviously don't apply here:

See?

So please enlighten me: how do I do this?

Thanks!
