When typing up a post, click the "Go Advanced" button to bring up the advanced post editor. There should be a hyperlink button, that looks like this:

Simply click on that, enter the text you want the link to say, then paste your link, and voila.

Alternatively, you can write the HTML tags manually, like this:
[url=http://www.ultimate-guitar.com]Link to UG

Here's what the result would look like:
Link to UG

Hope that helps.
