[xwiki-users] No jobs in the scheduler of the wiki instances in a farm

Hi, I 'm using XEM 2.3.1 and I discovered that, by default, there is no job task defined in the subwikis. In the main wiki, the 3 notifiers are present and notification by email works fine. So a user in a subwiki can't define a notifier because the listbox is empty. My questions : - Is it normal ? - Do I have to create manually the notifiers in each subwiki ? And how to do that ? If someone can help me in this summer period, I will be very happy. Maxime
