A web user is a user account within web server. 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).
To create a new web user account:
Click the
Web Users icon on the Domain administration page. The Web Users page appears: 
Click the
Preferences icon to configure web user access format and enable scripting capabilities. The Preferences page opens:
To allow accessing web user pages via URLs like webuser@domain.com select the corresponding checkbox.
Select the Allow the web users scripting checkbox to enable scripting for web users' pages.
Click OK to submit your changes.
To add a web user, click
Add Web User. You will be taken to the Web User Configuration page: 
Specify the name of the new web user, enter and confirm the password for web user, specify the hard disk quota, and select the available scripting options for the given domain (if enabled in Preferences).
NOTE
Each web user creates a system account within web server; therefore, you cannot have two web users with identical names on the same server.
You cannot use the reserved system words, such as "mailman" for user names.
NOTE
Do not use quotes, space and national alphabet characters in the password. The password length should be between 5 and 14 characters and password must not contain the login name as its part.
Once you have completed all entries click OK.
As you create web users, the user names appear listed on the Web Users page.
NOTE
New web users can access the directory using FTP software by entering the domain name under which the web user account was created and using the appropriate web user name and password.
