I am almost ready to launch my new Xenforo. Some of the Add-ons are not yet good enough to be added to my forum, but I would like to try them out as they get a little better. My question is: How do I test new layouts, add-ons and styles without disturbing the users on the forum with test threads, User Albums, XenPorta and so on? Are there a funktion to close the forum for all except the admin og can I make a test installation in a secret location on my server? Any advice is very welcome.
