The answers on your question depends on the architecture of your software - if you really expect to have a big site, you'll have to design the interfaces between the several components of your system, both on hard- and software level. Generally speaking I think it's easier to use one database per user - it increases portability and scalability - you'll be able to distribute your database servers easier. > I am thinking of having some file etc. "cms-core.php" in some base > directory and every subdirectory (= users subdomains) would include this > "cms-core" file with some individual settings. Is there better idea? Use WordPress ;-) Again, remember simple concepts of software engineering. Be careful to implement a system that depends on one component to work - this point'll easily become your single point of failure. I'm not just joking about wordpress, why develop another system in the wild world of open source CMS's? Take a look around - it'll save you loads of development headaches.
