+## 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]]

+I have a test ikiwiki setup somewhere to investigate adopting the comments
+plugin. It is setup with no auth enabled and I got hammered with a spam attack
+over the last weekend (predictably).  What surprised me was the scale of the
+attack: ikiwiki eventually triggered OOM and brought the box down. When I got
+it back up, I checked out a copy of the underlying git repository, and it
+measured 280M in size after being packed. Of that, about 300K was data prior
+to the spam attack, so the rest was entirely spam text, compressed via git's
+efficient delta compression.
+
+I had two thoughts about possible improvements to the comments plugin in the
+wake of this:
+
+ * comment pagination - there is a hard-to-define upper limit on the number
+   of comments that can be appended to a wiki page whilst the page remains
+   legible.  It would be useful if comments could be paginated into sub-pages.
+
+ * crude flood control - asides from spam attacks (and I am aware of
+   [[plugins/blogspam]]), people can crap flood or just aggressively flame
+   repeatedly. An interesting prevention measure might be to not let an IP
+   post more than 3 sequential comments to a page, or to the site, without
+   at least one other comment being interleaved. I say 3 rather than 2 since
+   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?
