Can you help me upload files to website? Please!

Hi there,

I'm not sure if this the right place to post my question...I'm hoping it will be all right!

I'm trying to figure out how to upload files to a website I help manage. They want a central place on the website where they can edit the documents that are collaboratively working
on. They also want a place to store them from year to year since they are probably
only used only once a year. (It's a horse thing and the documents are show premiums).

I'm guessing I do something in PHP...but what? I've played with some scripts, but I'm afraid with my level of...let me think... ZERO expertise I will be placing the server and the site in a vulnerable position. Is there a central place where I can get scripts or learn enough in a very short time to do what I need to do?

As far as security goes, how do I do a sign in screen prior to accessing the upload/download/storage page?

I really hope this makes sense...

Thanks for your help!

UPDATE: I'm just going to use my .mac account. Ta Da! It won't be million documents...I think it wil be fine.
