[xwiki-users] selected the informations tab as default on every pages

Hello all, I just start using xwiki and as every beginers I am stuck on seting up a tiny detail. My problem is the following: I would like the tab informations on every page to be the default selected tab. I try to look at the forum, and other related pages concerning xwiki configuration and all I founded is how to disable tabs but not modify the basic selected tab. I sure it is simple, but I don not know where to add the modification. Thanks for the help. Best regards Joseph-André GUARAGNA
