Dynamic Duo... who are you?

So, someone made a comment on my blog a little while back. The problem is, I don't seem to know who you are. :) Sorry for not knowing, but your blog is private and I can't get on to see who you are. So, until you identify yourself to me somehow, we will have to continue a coy little game of cat and mouse. You know me, but I don't know you.... who are you Dynamic Duo? I just don't know!
