A few suggestions for upgrading the user information page...most of these shouldn't be too hard to implement:
1) multi-page functionality for comments -- many of the more popular and most commenting contributors to this site have a lot of comments on their user page...on a slower connection it becomes a bother to thank them or get to the link to view their images.
2) "greeting" comment -- a new blank that would give the user whose page it is a kind of thank you for visiting my page.
3) use of author gallery thumbnail -- instead of using the generic painting with easel perhaps use the thumbnail chosen in caedes control for this.
