Disk Space includes all data in your home directory (including files owned by 'nobody') plus MySQL data and mailing lists. The disk space usage reported by the Control Panel does not include all data and may not be accurate.
Subdomain hosting is not allowed on our Shared Hosting plans (i.e. pointing domains to sub-directories).
We do not limit bandwidth usage. If you exceed your bandwidth quota, you will be invoiced for the additional usage. You can monitor your bandwidth usage in your Control Panel.
