List comments on the user profile page.
I'd like to see a history of comments posted (and for moderators, perhaps even including deleted comments) on a user's profile page.
Allow moderators to look over the totality of a user's behavior when deciding how to respond to reports of individual instances of behavior.
Allow me, as a user, to find comments I've made in case I want to review and revise them.
Allow any user who recalls who made an interesting comment but not where to find the comment.
