Links are pretty basic things but can also be very powerful in connecting people with the right information fast. Spike@School has two ways to add links to the site: A Link, and a Link Set.
A Link is used when you want to link to another site (or area within your site) straight from the index bar. For example, you might want to have a link to your webmail system appear on your indexbar. You'd use a Link for this:

We can see that the link now shows up on our indexbar:

A Link Set allows you to group a bunch of related links together. You can add a Set to any part of your site. For example, teachers could use them to add Links based around a particular subject their class is studying. Let's first add a Link Set:

We'll then add a couple of links to the Link Set:

On your website the Link Set appears like this:

We use a Link Set inside each of our Learning Caves and Staff Zones.
