To make a hyperlink like that, you use this code:
CODE
[url="page URL here"]Example Text[/url]
For example:
Click here!CODE
[url="www.google.ca"]Click here![/url]
You can also use the "Insert Link" tool (

) to help you with it. When you make a post, you should see that green icon above the part where you write your post. Click on it and do what it says and it'll put the code into your post.
