Enabling or Disabling Actions

You can reach the action admin list here.

One on the action list, you will see your list of actions:

To disable or enable an action, toggle the "on/off".  You can also search for "on" or "off" to see all the enabled or disabled actions.

If an action is disabled, it is IMMEDIATELY removed from the action feed for your users.  This is often the fastest way to remove things.
