Using the Manage Users link on the user panel will allow you to access the users in your system. If you don't have many users, you may see them on the list. As your site grows, you might get more users than can be listed on one screen alone.
To find a user, there are a couple of options available to you.
If you know the name of the user (or a portion of it), you can use search. Just type the name in and click Go. The user module will return a list of possible matches.
At the top of the Manage Users screen is a listing of letters A through Z. If you click on one of these letters, a list of users whose usernames starting with that letter will appear. Clicking on "ALL" will return the complete list again.
Sometimes the amount of users surpasses what you can view on the screen, even after a search. These users will be split up into pages. You can navigate through these pages one-by-one by clicking the left and right arrows or skip directly to a page by clicking on that number. If you want to control how many users are shown per page, click that number under Limits.
The Manage Users page allows you to perform a few quick actions on users. You can change a user's administrative status by clicking "Yes" or "No" under the Admin column. (Note: as mentioned earlier, this will change to a option to disable user accounts).
If you want to make changes to an user's account, click the "Edit" link. You will come to the same screen used in creating an user. Make your changes and click the "Update User" button.
You can also delete a user by click on the Delete link. You will receive a warning before the final deletion.
Finally, if you are a Deity, you can make a user one as well. Only a Deity can make another user a Deity. Do not make this decision lightly. That user will have full control of the site and, unlike other users, will have the ability to change or delete your account.
