Hi Patrick, It’s easy for you to customize your wiki to make that field required by editing the XWiki.Registration page. Actually I’ve just checked quickly that page and I see:   ## The email address field, regex checked with an email pattern. Mandatory if registration uses email verification   #set($field =     {'name' : 'register_email',       'label' : $services.localization.render('core.register.email'),       'params' : {         'type' : 'text',         'size' : '60'       },       'validate' : {         'regex' : {           'pattern' : '/^([^@\s]+)@((?:[-a-zA-Z0-9]+\.)+[a-zA-Z]{2,})$/',           'failureMessage' : $services.localization.render('xe.admin.registration.invalidEmail')         }       }     })   #if($xwiki.getXWikiPreferenceAsInt('use_email_verification', 0) == 1)     #set($field.validate.mandatory = {'failureMessage' : $services.localization.render('core.validation.required.message')})   #end So this indicates that the mail field is actually mandatory when mail verification registration is enabled… thus it should work normally… Not sure why it doesn’t in your case. You should open a jira issue explaining how to reproduce it (your setup). Now to make the email field mandatory is simple. Change the content from above with:   #set($field =     {'name' : 'register_email',       'label' : $services.localization.render('core.register.email'),       'params' : {         'type' : 'text',         'size' : '60'       },       'validate' : {         'mandatory' : {           'failureMessage' : 'Email is mandatory'         },         'regex' : {           'pattern' : '/^([^@\s]+)@((?:[-a-zA-Z0-9]+\.)+[a-zA-Z]{2,})$/',           'failureMessage' : $services.localization.render('xe.admin.registration.invalidEmail')         }       }     }) Make sure you save with a user having programming rights.
