Your site will have a few default contact lists, but you can make changes at any time.

Navigate to the Contacts Lists page

Go to: Communication Area > Contact lists
In the top right hand corner, click the link that says "Categories" - this is where the terms for contact lists are stored.

Add new, or edit or delete existing terms

Add a new term
Click the link to "Add term". Write a name. A description is not necessary and is only seen on this admin page. Click save.

Edit an existing term
Click the link across from the term to edit it. Remember to save your changes.

Delete an existing term
Click the link across from the term to edit it. At the bottom of that page, select "delete"

Change the order of the categories

Go to: Communication Area > Contact lists

In the top right hand corner, click the link that says "Categories" - this is where the terms for contact lists are stored.

This page lists the terms in the order they'll be displayed on other pages. Default is alphabetical. You can change the order using the cross arrows along the left side of the words. Drag and drop the words into the order you want.

Note
Do not "nest" the terms (placing one item within and below another, creating a "tree"). This will not work, and can lead to issues if the lists are used to send email.
