I added a new user but I can't assign them a task. What happened?

Intervals features project level permissions to give granular control over access. You may want to double check and make sure that the users are part of the project team. This can be accomplished by looking up the individual project and editing the project team or the person can be looked up from the people section. For your core team you may want to edit their profile and click on the “yes” option to “add to all future projects”. This will make is easier when creating new projects to always have your team associated.
