Once you have created and configured your groups, there are a number of ways you can maintain them on your site.
Quick Launch makes it easy to find the names of groups and open them, but you might not always want every group you access to be available in Quick Launch. For example, you might want to have quick access to the readers and contributors group, but you might not want to provide easy access to the administrators or designers groups:
On your SharePoint Site, click Site Actions and select Site Settings from the menu.
In the "Users and Permissions" column, click "People and groups."
On the "People and Groups" page, click Groups in Quick Launch.
On the All Groups Page, click Settings and then click Edit Group Quick Launch, as in Figure 12-10.
On the Edit Group Quick Launch page, in the Groups field, add the groups you want to appear by either typing in their names or searching for them, or right click a name and select Delete to remove it, as shown in Figure 12-11.
Click OK to save your changes.
In SharePoint you can use the Set Up Groups option to create a collection of new and existing groups and then assign Owners, Members, and Visitors to those groups:
On your site, click Site Actions and then select Site Settings from the menu.
On the Site Settings page, in the "Users and Permissions" column, click "People and groups."
On the "People and Groups" page, click on Groups in Quick Launch.
