I'm looking to setup a web file server so no more than 10 friends can access some files.

I need them to be able to access from web browser, most have IE but some have others.

I need them to be able to upload and download the files and it needs to be password protected.

Some people have already pushed me towards a windows home server system but I'm here to see if you can convince me otherwise

I've got resonable IT experiance (not much with ubuntu thou).

I have a spare computer if needed or my desktop.

I need my friends access to be easy e.g. I want to send them a web address they go to log in with username and password and they can see the folders with files in.

Any help or advice welcome I'm off for the next few days so I am free to have a play with Ubuntu.
