+>>> removed the done tag so this is visible as a patch. -- [[Will]]

+
+>>>>> I agree. I'm working on this for for both new pages and existing pages.
+>>>>> It shouldn't be hard once I get WMD going through the javascript API.
+>>>>> At the moment that is inexplicably failing, and I haven't had time to have a good look at why.
+>>>>> I may not get a chance to look at this again for a few weeks.
+
+>>>> Can I get a license statement (ie, GPL-2+) ffrom you for the plugin?
+>>>> --[[Joey]]
+
+>>>>> Certainly. You're free to use the code I posted below under the GPL-2+ license. You'll note
+>>>>> however that I haven't said anything about the WMD code itself. The WMD web page says:
+
+>>>>>> "I'm refactoring the code, and will be releasing WMD under the MIT license soon. For now you can download the most recent release (wmd-1.0.1.zip) and use it freely."
+
+>>>>> It might be best to contact <support@attacklab.net> to for an explicit license on that if you want to include it.
+>>>>> -- [[Will]]
+
+> So, I wonder if I should add a copy of the WMD source to ikiwiki, or rely
+> on the user or distribution providing it. It does not seem to be packaged
+> for Debian yet. Hmm, I also can't find any copyright or license info in
+> the zip file. --[[Joey]]
+
+>> This is a good question. My thought is that it will probably not be packaged any time soon,
+>> so you're better off adding it to IkiWiki. I'd contact the author of WMD and ask them. They
+>> may have more insight. -- [[Will]]
+
+Note that the WMD plugin does **not** handle directives. For this reason the normal `preview` button
+remains. Some CSS to clean up the display of the live WMD preview would be good.
+
+> Can you elucidate the CSS comment -- or will it be obvious what you mean
+> when I try it? Is it what's needed for the live preview? --[[Joey]]
+
+>> In the version of the plugin below, a new `div` is added just below the form. WMD
+>> populates this div with the HTML it generates from the Markdown source. This is not very
+>> pretty at the moment - it appears in the same place as the preview used to, but with no
+>> header or anything. Any standard IkiWiki preview will appear below the WMD live preview.
+>> I recommend having a look at <http://wmd-editor.com/examples/splitscreen>
+>> for what a little CSS could achieve. -- [[Will]]
+
+> Hmm, now that I've tried it, I notice that it does live preview by
+> default, below the edit window. Which is nice, but then if I hit the
+> preview button, I get two previews.. which is confusing. (Also, minor,
+> but: the live preview is missing the "Page Preview:" header.) --[[Joey]]
+
+> I wonder how annoying it would be to add some kind of simplistic wikilink
+> support to wmd's preview? And/or a wikilink button? While not supporting
+> directies is fine, not supporting wikilinks in a wiki seems a bit
+> lacking. It may also entice novide users to not use wikilinks and instead
+> use the hyperlinks that wmd does support. --[[Joey]]
+
+> Bug: When I preview, all the text in the edit field seems to be
+> converted from mdwn to html. I think that wmd is converting the mdwn
+> into html when the form is posted, so it would also save like that.
+> I assume that is designed for websites that do not use markdown
+> internally. Doesn't it have a setting to leave it as markdown?
+>> Found setting, fixed. --[[Joey]]
+
+>>> As I noted above, I've been working on the non-markdown page issue.
+>>> Below is my a new javascript file that I'm using, and below that a patch
+>>> to enable it. This patch makes the normal usage prettier - you get
+>>> a side panel with the live preview in it. It also adds a new config
+>>> option, `wmd_use101api`, which turns on code that tries to use the
+>>> wmd api. At the moment this code doesn't seem to work - moreover the
