How to add a new user in Pier?

Hi! I added one user once, but I forgot how I did it. I tried to add another one, but I am unlucky so far. Here is what I tried: - In _System Management, I press "add", but it seems I can add a page there, but not a user - In _System Management, I press "edit", this is to modify the page _System Management - In _System Management, "Setting" does not seem to let one add users - In _System Management/Users, pressing "add" is to add a page. I do not know what this mean. - In _System Management/Users, pressing "edit" is to edit the component page. - In _System Management/Users, pressing "setting" is to set something else than users. I tried similar "add/edit/setting" on Group, I haven't found the way to add a user. Am I doing something completely wrong? Is Pier suitable for a conference website ?
