'Happiness is an inside job'

Hi, I do have one quick question about the site. Is there an easy way to find costs that you make comments on?  A few times, I've made comments, but not remembered whose post it was, & then been completely unable to find those posts. I'm sure with at least some of them, if I saw the name, or the subject, or the first few words of the post, I would recognise it. 

Thanks, Lyn
