## user_admin_action

This hook is part of a series of hooks that allow you to add custom user settings. Consider a plug-in called "abc". In that plug-in, you want to save custom settings on a per user basis. Therefore, following our unpublished ? table naming standards, you would create a table called "abc_settings". When you tab over to the "abc" plug-in, you are provided an "abc settings" on the right similar to "Graphs". The next series of hooks allow you to present those settings to the user, enable or disable the users access to that specific "abc settings" tab and allow an administrator to define customer values for that plug-in on a per user basis.
