Hello, I’ve made a review over the extensions regarding Nested Spaces. The main interest were the methods relative to *space* notion and *parent/child relationship*. You can check the review made on : - bundled / installed by default extensions from XE at: http://design.xwiki.org/xwiki/bin/view/Proposal/XWiki+Enterprise+Extensions… - extensions from Contrib at: http://design.xwiki.org/xwiki/bin/view/Proposal/Contrib+Extensions+Review I am looking forward to your feedback and personal opinion on what aspects should I also review. Thanks, Gabriela *Gabriela Smeria* *Web Developer* gabriela.smeria(a)xwiki.com skype: smeria.gabriela
