I think it'd be a great module to have if I get it to work.
It does not work at all for me.
I've read the readme.txt and followed the instructions.
(by the way there is a typo in the readme.txt file, you say "replace yourtemplatename_ with blah blah" but there is no yourtemplatename_ within the code you give, what it's there is a yourthemename_ , I assumed this was a typo and replaced that)
I do see the Nofollow/Dofollow options below the submit button but they don't have any effect.
I use aberdeen theme and a multi-sites configuration.
I've also added the extra code you give in this other issue [#236441] for the primary links but doesn't work either :-(
It also creates another issue but I'll open a different support request for this one.
