I suggest this as 1.4.1 - it is fully based on REL1_4 .
E-Mail Notification for page and user-page changes and E-Mail-Address Authentication. Many further innovative features such as direct links to difference view between current and last-seen versions (of watched pages).
See http://bugzilla.wikipedia.org/show_bug.cgi?id=454 for further information and http://meta.wikipedia.org/wiki/Enotif (download, installation instructions, screenshots, documentation - there are already many pages; the pages refer to the last version but will be updated in the forthcoming days)
Comes with full installer and updater code, as usual.
Implementation details: It fully uses DATETIME type for timestamps. It uses again the effective user_newtalk table, which allows efficient memcaching for newtalk signalling. Sysops, Developers and Bureaucrats need _not_ to authenticate their e-mail addresses, when they enter or change them (for convenience; this can be switched on or off in DefaultSettings as many other options). On the Create Account screen you can now also enter the email address as you create the new account (this is an old bug of mediawiki, but solved within my ENotif patch).
Please may I ask you, that you add your e-mail address to the CC list of http://bugzilla.wikipedia.org/show_bug.cgi?id=454 , if you want kept up-to-date ? This saves my time for writing to the many different "channels".
Avoid the most common pitfalls when you want to test E-Mail Notifications as a newbie to it: ===================================================================== 1. Do not forget to enter an e-mail address (user preferences) !! 2. Be aware, that you never receive an notification for your own changes (you need to log in as another user B to invoke and check ENotifs sent to watching user A ) 3. ENotifs are sent only for the first change on a page you are watching 4. ENotifs are automatically retriggered when the watching users visits the current version - may be direct or indirectly by visiting the difference to it.
