SLA24 Service Desk has an extensive suite of options that control the behavior of user registrations. To access these, go to the TICKETS->SETTINGS->REGISTRATION tab.
Allow Registrations: This is self explanatory – it allows you to control if users can register themselves or if they will only be shown a login screen.
Who Should Receive New User Notifications: Control who gets the standard WordPress registration emails – admins, user, both or none.
User Name Construction: This is a long list of options that give you control over how user names are created when a new user registers using the SLA24 Service Desk registration page.
Registration Field Descriptions: Use this section to add a descriptive text under each registration field.
You can replace the registration screen with a custom screen. If you are using a 3rd party registration screen you can tell SLA24 Service Desk about it in the TICKETS->SETTINGS->ADVANCED tab. Look for the option titled Custom Login/Registration page.
