Hi Rob,
You can instruct MediaWiki to require verification of
email addresses
entered in user preferences. With a little hacking, you could modify
the login functions in User.php to check the user's validation hash,
and see if they've been validated. If not, then you would reject
login.
Thanx for that. I will have a look at the User.php.
Do you know of the top of your head what the string is that I need to verify?
I am a little surprised that this is not default functionality. :)
