To create a survey campaign, you simply need to add a survey to a project.
You must be a Project Manager or Organisation Admin to add a survey to a project
Every survey has its own survey show page
E.g. https://staging.makerble.com/story_categories/508
In the right column is a box called Survey Campaigns which lists the projects using that survey
Clicking the title of any of those projects will redirect to the Survey Campaign page for that survey on that project
At the top is the Add to Projects button which allows you to add that survey to one or more projects
Add to Projects popup
This lists the projects that you are a Project Editor of. If you are a Charity Editor, it will list all the projects in your charity.
Select the projects that you want to add the survey to
Projects of yours that the survey has already been added to are already ticked and disabled in the list
