Ok now i should tell you how to implement the do follow attribute in your blog
As i always say open up your template html.
<a expr:href='data:comment.authorUrl' rel='nofollow'<data:comment.author/></a>
Delete the one in Bold and you are done..
I suggest you to remove all the rel='nofollow' tags in your template so that you can make sure of it..
I have removed all the nofollow tags in my blog template..So comment on.I am waiting for yours.Any suggestions questions or anything will do.. Update: The comments here are no longer DO FOLLOW
