Force the nofollow and new window on all outbound links.
To avoid Google bans when you have outgoing links considered as paid links, you must add the rel="nofollow" to every outgoung link. This plugin adds it for you.
If you want outgoing link to open in a new window, this plugin add the correct attribute to every link it finds.
Links manipulation is limited to post content links.
