Hy, I am a new XWiki Workspaces user and I have many questions to ask you. :) How to delete a member? How to change the login's member? How to deploy a new XWikiWorspaces version (ex 1.0 -> 1.1) without erasing current spaces and members but take new fonctionnalities into account? How to activate the administration tool bar in spaces were member is administrator (cf attached file) ? Thanks for your lights! Nicolas
