Your project page is only available to others when you publish it.
When you are at the stage of the campaign page creation, only the person creating the page can access it, when correctly logged with the Ulule account.If you assign an Editor role to users, they can also access your project page. Any other person who would try to access the page before publication would get the following error message instead: "You don't have the permission to see this page!".
When your page is published, any person with the direct link can access the campaign page. Please note that the page will be visible in Ulule search result pages when you will have a minimum of 5 contributions on your page (Learn more about the Nestling mode).
