CommentLuv Problem?

I use the no/do follow plugin for firefox (pick one) for Blog Make Money so that my commentators will get dofollow links on my blog, a benefit to potential friends considering my site's angle. It could be helping my site have some life and to get feedback but it doesn't seem to be working.

I did register at the site*
I did enter the fields etc*
But no comment luv functionality?

The button is under the comment field, and I uglied up my info section (Do I have to have that button on there to stay a member? Do I just need to be logged in there with an active cookie from them or something or else dofollow doesn't work - is it a force for them to get members? I only have the one comment, a friend who saw a tweet, and one from myself, but if anything my own link on my own comment luv and [possibly overlooked setting] seemingly good configuration should be dofollow, right? What should I do? Lose comment luv and dofollow? Just use top commentators instead?)

Should I just use the top commentators widget alone?
