Please take a minute to answer this, I'm receiving
similar requests for
activating Special:Wantedpages on the Romanian Wikipedia as well, and
I'm not sure why this has been disabled -- or whether it can be re-enabled.
Try asking on bugzilla.mediawiki.org
(use the category "Site
request"). If it can be re-enabled, someone will probably do so, if
not, they should at least give you a reason.
