Definitely Janet, my personal suggestions would be to leave the link normal unless you don’t want to share some google love. 🙂 For example, I try to do nofollow to links that don’t need any more rank, like wikipedia, amazon, etc. I also do nofollow whenever there’s a link that is affiliate. Besides that I leave the links as they are. Google also looks at the different ways you use nofollow to rank your own website.
