1 I'd strongly recommend this modification to ikiwiki. Any particular limitations that anyone can think of?
3 I might even have a try at this patch, though I'd have to hack the user preferences page to include author name...
5 As to the question of whether the committer was the 'script' or the wiki editor... I'm not sure. Marking it as the script somehow (`ikiwiki-cgi <ikiwiki@sitename>`)? seems to make sense and would make it easier to manage.
