CommentLuv question

Hi.
I have a pr 2 blog with some comments on my pages, some days ago one of my friends told me to use commentluv plugin to get more comments.
Now i just want to make sure this plugin wont decrease my pr or anything like that

Anytime you allow outbound links you are basically allowing your page rank to flow out of your site. So long as it's not excessive it's nothing to worry about, but if too many people are commenting and getting d0f0llow OBL then yes, you're hurting your rankings.

Yeah either make them nofollow by default or just make your own comments. Only if there's links in the comments it would have your linkjuice flow away..
