I’ve been looking out for something like this for a while now. WordPress by default has a number of (not very useful IMO) relationships or ‘rel’ checkboxes you can select for various link relationships but rel=”nofollow” is not one of them.
All the plugins I looked at put the “nofollow” attribute on ALL links – you can’t select which ones you want.
Turns out you can easily add this option with a few lines of code. Without further ado, here’s where I got the idea and code from for this blog: How To Add “nofollow” To Certain Blogroll Links In WordPress 3.x
