Default to Approve

From PluginWiki

You can make the plugin default to Approve on Pending Messages or Pending Members.

This won't automatically approve all of them - it just means that's the default for when you hit Save Changes.

If you enable this function, remember that instead of you individually changing Pending Messages Status or Pending Members from 'Pending' to 'Approve' (the normal behaviour of Yahoo), the full page will be approved when you hit 'Save Changes'. Anything you don't want approving must be changed to 'Pending' before you hit 'Save Changes'.

You can configure this on More Advanced Options from the Features tab.

If you use Holding Messages, then held messages won't be set to Approve.
