To edit your "Links" section, first click on the menu and scroll down to "More." Click "More" and then click "Links" and you can now edit the links you are including in your links section.
Organize all your links in one place. You can setup different "link" categories for different users; i.e Students, Teachers, Parents.
If you have the "Links" module on your home page, you can select "Display On Homepage" to add it to the list of links displayed on the homepage. This is per each "link" added, so not all of your links will be shown on the homepage, only the ones you select.
