Overall Requirements

1.Support of multiple languages (Language configuration files and all description text as variables)

4.Do use div for html layout and code HTML so that can be modified easily by CSS - avoid tables as layout tools

5. Avoid using platform dependent functions/libraries

7. Store only password hash and compare hash
