This is a great plugin but there is something going wrong when used with other plugins already adding nofollow to links by default. For example Author hReview adds nofollow by default and for good reasons.
I also noticed that if there is nofollow already in the link, eg inserted there manually, the plugin isn't smart enough to "respect" that and stay away from this extrernal link.
This whole things creates double nofollows and double target tags.
Any ideas if there're will be a fix ?
