In the ISPconfig panel you can create Resellers, Clients and Hosting plans.. If I assign 10 GB to a Reseller, he'll be able to divide that space as he sees fit between his users. If I assign 1 GB to a client, it's his. If I assign 1 GB to a Hosting Plan, how is it used? Every user with that hosting plan has that much space, or is it divided as with resellers? Is there somewhere I can read up on that?
