Neato. Works at pmwiki.org now.

Or I could add some string to my post action? The code looks like this:

		     (http-post
		      (pmwiki-loc 'base) ;; Get destination
		      (list (cons "pagename" pagename)
			    (cons "action" "edit")
			    (cons "post" "1")
			    (cons "diffclass" diffclass)
			    (cons "author" pmwiki-author)
			    (cons "text" (buffer-string)))
		      'iso-8859-1
		      headers)))))

so I suspect it's just a matter of inserting something like:

			    (cons "User-Agent" "Emacs/pmwiki-mode")

Does those strings look ok to you?
