OK, let say I have to setup a Single Server, with no real Hosting Clients, just a TLD for one Company. According to Chapter 4.5.1 of the ISPC Manual, I could setup all services to the Admin. Just, if I would split the Admin Power from within the normal User Power, the use of a Single Client may be sufficient? If it would be, could I just use the TLD (same as the one for the Server/ISPC as a Domain for that 'Client'? If yes, I could just do the setup for Website, E-mail and so on using the Server/ISPC TLD, like http://server.com? The Nameservers would be the Nameserver from the Registra. Please let me know if using the above way will be OK or not, or what I've to be aware of. Thanks a lot for any advice.
