Pingcrawl

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

The standard WordPress trackback link behavior does not provide users their expected result. wp-TrackbackPopup resolves this issue.

Scans post for links, checks if they are pingeable and sends pingbacks with results returned, improves chances of successful pings!

Adds the ability to publish a post without triggering pingbacks, trackbacks, or notifying update services.

SMu DoFollow has many DoFollow Options (Manual or Automatism) and included URL Validator (Manual, WP-Cron or Cronjob).

One step process to remove pingbacks and trackbacks and leave only real user opinions in your posts comments.
