+## Syndication autodiscovery for comment feeds
+
+A standard `\[[!inline]]` directive adds links to the autogenerated syndication feeds using link tags in the header:
+
+ <link rel="alternate" type="application/rss+xml" title="$title" href="$page.atom" />
+ <link rel="alternate" type="application/atom+xml" title="$title" href="$page.atom" />
+
+These links aren't added to my pages that include comments even though comments generate syndication feeds. How can I configure the comments plugin to add these links to the header? (These links are required for user-agent autodiscovery of syndication feeds.) --[[anderbubble]]

## Moderating comments from the CLI
How do you do this, without using the UI in the Preferences?
correction follow-ups are common.

+## Comment threads
+
+Any thoughts about implementing some simple threading in the comments?
+
+Or at least a reply functionality that quotes the subject/contents?

+## 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?

+## Keeping comments separate from content to avoid triggering rebuilds
+
+Is there a way of preventing comments from triggering long chains of rebuilds? Currently comments trigger the same chain of events as if the page itself had been modified (at least this seems to be the case). A way of keeping comments lightweight and out of ikiwiki would be great. This has obvious consequences but currently comments are to slow for my users. My site is complex with tags and trails (albums) so commenting the wrong page leads to several minutes of rebuild (being conservative here...). For my use case comments don't need wikilinks or any wiki features.
+
+To my thinking it could be useful to have comments as a very lightweight type of data that enables interactivity but not the full force of ikiwiki. Any thoughts?
