Why do I need to add user and what is this for?
If you want your colleagues to be able to edit your plans, you need to create accounts for them.
How many user accounts do I need?
It depends on your team and you can add up to 20 users.
Sharing is not enough?
When you share the file, your colleagues will not be able to edit your files but comment and print it.
Why is it good for me?
Sharing your login details is not secure.
Adding sub-users, you will be able to manage your team and have control over the users' access rights. You can set if they can delete, create or upload files.
