For a while, I’ve been a bit annoyed with WordPress losing pings (those automatic links on your blog when someone links to you) anytime someone links to more than one of my posts. It turns out WordPress’s comment flood prevention is getting in the way. This plugin prevents WordPress from discarding these pings.

WP_PingPreserver

Prevents WordPress from eating pings that come too quickly in succession (i.e. a single post linking to more than one of your pages).

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