Gliffy also offers you the ability to Add or Remove users from the Account Settings menu if you are an administrator of the account and you have a multi-person plan.
Users with Admin rights can add new users to the account by entering the email address of the personin the add box and clicking ‘Add’ button located on the right.
Once a user is added they will be sent a welcome email to the email address entered. This welcome email will contain the account name, email address, and a temporary password (if the user is not already listed under another account).
Users with Admin rights can remove a user from the “Users” menu by clicking the “Remove” link and they will no longer have access to the account.
