Easy way to find specific commentators?

Is there an easy way to find a comment from a specific member or from TF? For example, on main street, if I want to find TFs comments after the main post, I have to scroll through all the comments until I find any that may be there. This is actually not that bad, since his comments are in yellow. But searching for a specific member, especially on active threads such as Palins trading corner can be tiresome. I've tried to go to an individual members page and click on history, but that just lists the threads in which the member has posted, with no easy way I can see on how to get to that members own posts. Am I missing something? Thanks Eric
