I did write it in a bit of confusing way. What i was saying is that i cannot offer a hosting packet to my clients with let's say 5 subdomains and 50MB of webspace and 50MB of bandwidth total per domain + all 5 subdomains.
Why not? Cause each subdomain will have its own limits in webspace and bandwidth and the reason for that is that we actually create new account for subdomain completly seperated from 'main' account.
Actually i can't even offer them additional domains to be used on the above hosting packet. Same thing, new account for each domain and each domain gets again 50MB of space and 50MB of bandwidth, less or more, depends on how much space i give them.
