Hello, I deny(or just keep blank) Register right for XWikiAllGroup<http://www.mandubian.org/xwiki/bin/view/XWiki/XWikiAllGroup> Then I deny "register" right for "unregistered users" aka XWiki.XWikiGuest I logout It appears that anyone is able to register!!!!!!!!! Then, I allow register right for XWikiAllGroup while keeping it denied for XWikiGuest. The register menu disappears by default! Apparently, the right management requires the right to be defined at least for XWikiAllGroup to take XWikiGuest into account. is it normal? best regards Pascal
