To edit one or more official(s):

1. Go to the officials roster (Directories -> Officials)
2. Click the selection box in the rightmost column for the desired official(s)
3. Click the "Edit Official" button
4. Make the desired changes
5. Either click "Update this Item" or (from some types of fields) press "Enter"
6. The page will reload with the next selected official, or, if it is the last selected official, will disappear and return you to the roster

Selecting more than one official in step 2 is the most efficient way to edit multiple officials.
