I hope I will not be off-topic with my question/issue...
Since the teachers of my university do not want to have their lectures to be public, I had to restrict the access to even readers (before only editors had to be registered, now this includes also readers, unfortunately). However, since the access requests of the students will probably (and hopefully) skyrocket, I found about the EmailDomainCheck extension that I setup on my test wiki.
However I noticed that if in LocalSettings.php I passed: $wgGroupPermissions['*']['createaccount'] = false;
$wgGroupPermissions['*']['createaccount'] = true;
People had just to give any e-mail address (even a non-existing one), having the correct domaine name and they would be registered with a welcome message and already logged in, thus bypassing the EmailDomainCheck extension.
Is there a way to restrict the account creation so that people have to click a button that sends the login credential to the mentioned e-mail address?
Thanks in advance and best regards, pdeli
