Root level 'home' folder

Hi,

When I cd in Terminal to the root level of my start-up disk, I see there is a folder called 'home' that is invisible in the normal run of things.

It would be really useful to me if I could create a folder with a MySQL connection script in there as I could then exactly mirror the set-up on my remote host.

But I'm no UNIX guru and I'm scared of tampering in these invisible folders so can anyone advise if it is okay to create folders in there?

Thanks,

Pat
