Customer template field clarification's

[RhysG]

Please can I get some clarity on the following field's in the customer template
1. Physical hosting management - this is the ability to create hosting account, but what is a hosting account
2. Hard disk quota assignment - does reffer to the HDD quota of a domain not the customers own quota, and I am assuming if it is a domain quote the domain can not exceed the customers quota?
3. Limits adjustment - does reffer to the limits of a domain not the customers own liits, and I am assuming if it is a domain limits the domain can not exceed the customers limits?

Thank you
