+## Disabling certain formats for comments
+
+It seems that comments plugin allows using all enabled formats and
+there is not way to disable some of them. For my blog, I want to use
+additional formats for writing posts but I do not want commenters to
+use those formats because it would be a security problem.
+
+Any suggestions or hints how to implement this?

+## URLs in anonymous-style comments committed directly via VCS
+
+[[!template id=gitbranch branch=schmonz/comments-anonymous-url-vcs author="[[schmonz]]"]]
+
+I recently imported my site from Textpattern into ikiwiki (using
+an `ikiwiki-import` program that may someday make its way into
+ikiwiki proper). Textpattern's comments behave much like ikiwiki's
+anonymous comments, so piping each imported comment through
+`ikiwiki-comment` and regenerating the site with `comments_allowauthor=1`
+preserved almost all the information.
+
+What's missing: if a comment directive has a `url` param, I'd expect
+the rendered page to href the author's name to that URL. This works
+as I expect for new comments added via the CGI, but not for imported
+comments added via the VCS directly.
+
+My branch has a fix that doesn't break `t/comments.t`, doesn't
+appear to break anonymous or signed-in comments via the CGI in any
+way I've tried, and lets me render my (incredibly valuable ;-)
+imported blog comments with full fidelity. OK to commit?
