Hi marquise and welcome to Tiki Community!
Yes, there is one profile to do that:
It's also devoted to easying the task to add comments to a user homepage while keeping those comments public, like the "Facebook wall" or similar features in some common social networking sites (hence, it's name: "Social Networking in Pretty Tiki Trackers", SNiPTT)
Please, provide feedback here or to its author (luciash) so that he knows easy ways to improve it, based on new users applying that profile nd sharing your first impressions.
I'm in process of using this profile for production also in short, together with an upgrade to one site that I'll do in the followiong weeks.
