* Add `COMMENTOPENID`: the authenticated/verified user name, if and only if it was an OpenID
* The default template should have a (?) icon next to unauthenticated users (with the IP address
as title) and an OpenID icon next to OpenIDs
+* Should the comments be visually set off more from the page above?
+ Rather than just a horizontal rule, I'm thinking put the comments
+ in a box like is used for inlined pages.
+* Instead of just a link to add a comment, it could have a form to enter
+ the title, similar to the form for adding a new blog post.
+* If a spammer posts a comment, it is either impossible or hard to clean
+ up via the web. Would be nice to have some kind of link on the comment
+ that allows trusted users to remove it (using the remove plugin of
+ course).
