Version 2.1 of my Related Posts plugin fixes an issue with WordPress 2.6. With the introduction of the new revision system, the plugin would create relationships with all revisions of a post when editing.
If you have encountered this issue, update to 2.1 and just remove the bogus relationships manually.

Kid,
If I wanted to no follow the related posts links could I do that? If so, where do I find the code in the theme for related posts?
