[xwiki-devs] [Regarding XWiki.Registration ] Hi devs@xwiki.org

Hello devs@xwiki.org<mailto:devs@xwiki.org> I has a question for the XWiki.Registration I tried to add input validation for the registration and it seems the following link has the information about it. http://extensions.xwiki.org/xwiki/bin/view/Extension/Administration%20Appli… When I read this document, there is the text like: Things which you may configure by editing XWiki.Registration However where can I find XWiki.Registration ? Is it configuration file ? I already check Registration section of the Administration Interface but I can not find. Please let me know where can I find XWiki.Registration. Thanks Kwan
