Thread:Extension talk:AddThis/Customize buttons in header/sidebar

If you're like me and feel that there are too many buttons on the default header box or would like to customize which buttons appear, you can edit addthis.php. Look for: $wgAddThisHServ = array( 	array( 'service' => 'facebook', ), 	array( 'service' => 'twitter', ), 	array( 'service' => 'email', ), 	array( 'service' => 'favorites', ), );
 * 1) Toolbar settings.  In this example, only the Facebook, Twitter, email, and favorites buttons will be shown:

The sidebar can also be edited in a similar fashion. I believe the names that are used for "service" match up with the ones used by AddThis.com.
