The easiest way is to use the hyperlink button when you reply.
It's next to the VB code box when you reply to a post. It says
http://
When you click on it a script prompt box will pop up. In that box type out what you want the link to say. Then another box will pop up. In the second box, type the URL of the post where you want the link to take you. The software will do all of the coding for you.
