Do you need any help with settings?
When adding a user, is there a way to globally assign all projects or do you have to add projects to that user individually?
You can assign all of them
while adding the users you have this checkbox, that says "assign to all projects"
Simply thick it
I thought I had checked that but when I look at the user I just added, it says that user has 0 projects. Can I go update his profile to assign him to all projects?
You would need to remove him and add him one more time
