Thanks a lot Devs. You have been very helpful As an administrator, I see that rights can be assigned on a user basis and on a group basis. What are the rules for assigning these rights if an ordinary member (showing up in the users list) also belongs to a group. I am guessing that anyrights applied to the group automatically apply to all users in the group BUT they do not show up the indivdual users list ! Also, can a user be a member of more than one group ? I realized that just assignig the global rigths /user rights are not sufficient! Space rights also matter! Is there a way to assign edit/view rights for a group in any space. For example, if we take the Todo application. There the creator has an option fo choosing the space in which he wants to create a new Todo object. If the user chooses a space where he does not ahve edit/view rights, it's not going to work right! It throws error 9001. so, how can we ensure that groups get rights on the newly created spaces? On another note: I used the following in the HTML code for creating a form for creating a new object: Here I assign the parent of the newly created page as "Main" But, the page actually gets created in the XWiki space. Is this because the class I am using belongs to the XWiki space ? I understand that an Xwiki Page is actually an Object. But then how does XWiki allow one page to contain multiple objects at once (like commments and Tags etc...) Or did I understand it wrong? '<input type="hidden" name="parent" value="Main"/> <input type="hidden" name="template" value="HybridPublishClassTemplate"/> <input type="hidden" name="sheet" value="1"/> Thanks again Devs.
