This plugin will modify the links on pingbacks (and trackbacks) to remove the 
“external nofollow” for links to your own blog.

Follow Self Pings

Tanner Moushey

Custom Pingback Email adds a new field to the General Settings page to specify a custom email address to send pingbacks and trackbacks to. This disables notifications for the default site admin and the post authors for Pingbacks and Trackbacks.

Custom Pingback Email

Add the option for a pingback notification to go to an email other than the site admin email.
