I asked Brion several times to implement is as http://test.wikipedia.org but the developers disregard (don't like) my "zoo" of enhancements.
You seem to have done a good job on coding, but I have heard no word on implementation.
The ENotif code v2.x is in CVS HEAD since December 2004 and I recently published my improved version ENotif v3.x for MediaWiki CVS REL1_4 (= 1.4.1/1.4.2), see http://bugzilla.wikipedia.org/show_bug.cgi?id=454 . Download address is http://www.wikinaut.de/mw/mw142+enea.tgz (repeated here for your convenience).
Worldwide several users of MediaWiki 1.3.7+ENotif2.00 appear to be very content with it, but are quiet :-)) Tom
