[xwiki-users] How can I forbid Users to create spaces

Hi! I have two questions: - As already mentioned in the subject, I want to forbid users to create spaces, only some user groups should be allowed to create spaces. - How can I make some spaces like xwiki, Main, and especially Panels, Stats invisible for any user except the admin user. I do not want them into index or even when in the search. Is this possible? Thank you for your help, Florian ------------------------------------------------------------------ Florian Rhomberg Gletscherblick 38 A-6080 Igls E-Mail: mailto:[email protected] www.nettania.net ------------------------------------------------------------------
