Client Templates: What's a "Web User"?

[epretorious]

I'm configuring Client Templates for the first time and am puzzled by the term "Web Users." What is a Web User?

From the admin manual:

Managing Web Users

A web user is a user account within Apache. It is used to define locations for personalized web pages with individual FTP access. The result of creating a web user is a subdirectory within your domain (e.g. domain.com/~webuser).
