+* [[Plugins]]
+
+ Plugins can be used to add additional features to ikiwiki. The interface
+ is quite flexible, allowing plugins to implement additional markup
+ languages, register [[PreProcessorDirective]]s, hook into [[CGI]] mode,
+ and more. Ikiwiki's backend RCS support is also pluggable, so support for
+ new revision control systems can be added to ikiwiki.
+
+* [[todo/utf8]]
+
+ After rather a lot of fiddling, we think that ikiwiki correctly and fully
+ supports utf8 everywhere.
+
+* [[w3mmode]]
+
+ Can be set up so that w3m can be used to browse a wiki and edit pages
+ without using a web server.
