+* [[SubPages|SubPage]]
+
+ Arbitrarily deep hierarchies of pages with fairly simple and useful
+ [[SubPage/LinkingRules]]
+
+* [[blogging|blog]]
+
+ You can turn any page in the wiki into a [[blog]]. Pages matching a
+ specified [[GlobList]] will be displayed as a weblog within the blog
+ page. And an RSS feed can be generated to follow the blog.
+
+ Ikiwiki's own [[TODO]], [[news]], and [[plugins]] pages are good examples
+ of some of the flexible ways that this can be used.
+
+* [[tags]]
+
+ You can tag pages and use these tags in various ways. Tags will show
+ up in the ways you'd expect, like at the bottom of pages, in blogs, and
+ in rss feeds.
+
+* Fast compiler
+
+ ikiwiki is fast and smart about updating a wiki, it only builds pages
+ that have changed (and tracks things like creation of new pages and links
+ that can indirectly cause a page to need a rebuild)
+
+* valid html and css
+
+ ikiwiki aims to produce
+ [valid XHTML 1.0](http://validator.w3.org/check?url=referer).
+ ikiwiki generates html using [[templates]], and uses css, so you can
+ change the look and layout of all pages in any way you would like.
+
+* [[BackLinks]]
+
+ Automatically included on pages. Rather faster than eg MoinMoin and
+ always there to help with navigation.
+
+* [[PageHistory]]
+
+ Well, sorta. Rather than implementing YA history browser, it can link to
+ [[ViewCVS]] or the like to browse the history of a wiki page.
+
+* [[RecentChanges]], editing pages in a web browser
+
+ Nearly the definition of a wiki, although perhaps ikiwiki challenges how
+ much of that web gunk a wiki really needs. These features are optional
+ and can be enabled by enabling [[CGI]].
+
+* User registration
+
+ Can optionally be configured to allow only registered users to post
+ pages; online user registration form, etc.
+
+* Discussion pages
+
+ Thanks to subpages, every page can easily and automatically have a
+ /Discussion subpage. By default, these links are included in the
+ [[templates]] for each page.
+
+* Smart merging and conflict resolution in your web browser
+
+ Since it uses subversion, ikiwiki takes advantage of its smart merging to
+ avoid any conflicts when two people edit different parts of the same page
+ at the same time. No annoying warnings about other editors, or locking,
+ etc, instead the other person's changes will be automatically merged with
+ yours when you commit.
+
+ In the rare cases where automatic merging fails due to the same part of a
+ page being concurrently edited, regular subversion commit markers are
+ shown in the file to resolve the conflict, so if you're already familiar
+ with that there's no new commit marker syntax to learn.
+
+* page locking
+
+ Wiki admins can lock pages so that only other admins can edit them.
+
+* Full text search
+
+ ikiwiki can use the [[HyperEstraier]] search engine to add powerful
+ full text search capabilities to your wiki.
+
+* Commit mails
+
+ ikiwiki can be configured to send you commit mails with diffs of changes
+ to selected pages.
+
+* [[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.
