Hello all, great forum!

Here's my situation:
I've got a dual-boot system (I can't fully let go of Windows yet) and I want to be able to share files between Fedora and Windows. So I created a vfat partition. To test it I went to Windows, found the drive, threw some files on it, then booted Fedora, mounted the drive and everything was there. Great! I created a 'shared' folder in my home/ directory, changed the permissions so everybody could read/write/execute, and edited my etc/fstab file so I didn't have to manually mount the shared drive every time I booted. But now I can't write to /home/shared -- the permissions (I think) were changed when the partition was mounted. How can I avoid this?

P.S. Here's what my new fstab line is:
/dev/hda3 /home/shared vfat defaults 0 3

Thank you Komakino, what did that do exactly?

the user option means that normal users can mount/unmount and generally access the drive. The man page says:
The umask=0 sets the bitmask for permissions that are not present on the mounted filesystem (and applies specifically to FAT based filesystems). I think having user and umask=0 together means firstly that the filesystem can be mounted by any user, and that they then have read/write and execute permissions on it.
