To limit the amount of resources a site can consume:

1. Click Domains, and then click the domain name you need.
2. Click the Resource Limits icon.
3. Adjust the following settings as required:

   - Maximum number of subdomains. Specify the number of subdomains that can be hosted under this domain.
   - Maximum number of domain aliases. Specify the total number of additional alternative domain names that can be used for this site.
   - Maximum number of Web users. Specify the number of personal Web pages that the domain owner can host for other users under his or her domain.

At the end of the term, the domain (Web site) will be suspended, its Web, FTP and mail services will no longer be accessible to the Internet users, and site owner will not be able to log in to the control panel.
