How to Use Links in WordPress
From Codex
The blogroll is a WordPress feature that allows you to store a set of external links. These links can be organized into categories. Links and their categories can be added, deleted, and edited.
Clicking on the "Links" tab in the Admin WordPress Panel will send you to the Manage Links SubPanel. The Subpanel contains a list of all of your links. You can choose to modify one link only or many links at once by using the options found at the bottom of the SubPanel.
The links will come in handy for a widget feature called Links. Going to Widgets in the WordPress backend, you will see a widget called links that can be dragged and activated in any widget section. This will allow you to display a selective group of links on your web site.
