Adding a link is a fairly easy thing to do. Here is how you make a link using the word box.
This icon on the word box creates a link. Highlight the text you want to be a link, then click this icon. You will be taken to the "Link" window as shown below.
All you have to do is paste the url of the link you want to use into this box:
Select "OK" and thats it!
To make your links look nicer, you don't have to type the actual link into the wordbox. For example, say you want to provide a link to PageBuildr merchandise. Instead of doing it this way:
You could highlight the word merchandise, click the link button, then paste the url in so that it appears like this:
"hey, did you see that PageBuildr has merchandise!"
You can also do the same thing with pictures! Just highlight the picture and follow the same procedure. The user can then just click on the picture to go to the link (great if you use the URL of a video as a link!).
Another button that may come in handy is the remove link button:
Highlight the region that you have linked, then click this button to change it back into regular text.
