I'm unclear on what is considered acceptable use of the Multiple Domain feature. Can I host domains that are registered to other people? Can I legally charge someone a monthly fee for hosting their site in my space? If so, and if I allow them access to their site, are there security features available to limit their access to their files only? I realize bandwidth and storage limits would be shared by all domains. Are there other considerations I should have regarding hosting other people's domains in my account?
(New to hosting, domain name virgin, please be kind and clear, thanks.)
