How to create a public folder?

[MrYogi]

How to create a public folder that about 12 people can access?

Should I build a fileserver?

Should I go with Mandrake Linux? Does it give me an option of installing the OS for a file server? How good the system should be?

Does AMD Duron 900MHz, 256 MB work ok as a file server?

Sorry for the bombardment of questions.

Thanks in advance.

Make a password protected share in windows and only give 12 people the password.
