directory – file upload

Hello and thank you for your plugin.
I have to ask few questions:

1) What should I do in order to make people able to upload their picture?
I set “home/website.it” as file upload path, but I get
“Impossibile creare la directory website.it/applyonline. Verifica che la directory madre sia scrivibile dal server!” (directory website.it/applyonline impossible to create. Verify that the main directory is writable by the server) [my domain is set instead of “website”]

2) is there a way to combine more form? I’d need to put a generic form (with name etc) on each ad and yet add a specific form in every ad with specific questions related to each positions

3) date picker is not working. tried many times: the calendar appears but the date is not selectable. what am I doing wrong?

Thank you very much
