I just hacked up a new special page for listing the deleted
contributions of a user. This has been a commonly requested feature for
over a year, but for various reasons nothing much has been done about it
before.
The code is in svn: see
<http://svn.wikimedia.org/viewvc/mediawiki?view=rev&revision=17968>. As
of this writing, it's not live on Wikimedia servers yet.
The page is accessible to users with deletedhistory privileges, i.e.
normally sysops. There is no link to the page anywhere (except
Special:Specialpages) yet; what I'd like now is some testing, review and
improvements before the feature is officially announced.
So, have at it!
(P.s. see also <http://bugzilla.wikimedia.org/show_bug.cgi?id=1699>.)
