If anybody can help me with these topics I'd greatly appriciate it.
A few specific questions:
What is a .mdu file extension?
How does the CHMOD work with owner and group level access?

ok..
why to a text file? you haven't got access to a database?? most hosts will have at least MySQL installed...
easier to access, password protected...
but if you really need to use text files... php has a crypt() funtion...
link to crypt() description on php.net
.mdu.. not idea... couldn't find anythign on the net about it... usually filext.com helps me out with that...
chmod is a command you use to change the permissions...
4 = read
2 = write
1 = execute
so chmod 755 is owner can do all... group and public can read and excute...
in general you can treat group like you treat public.
in general leave owner (you) set to 7 unless you want to stop yourself from editing the file.
