Sometimes if you want to enable an extension, turn on site-wide scripts, or turn on discussions, you need to contact the staffs and this could be further simplified.

These requests can be made into buttons. Requests can be revoked in any time. Once the requested feature is enabled, the button will disappear, and you will be notified via the notifications menu.

The buttons are stored in a Special page.
