Hi Tony,
I've already had a look at Gerrit's explanation and it certainly clears things up. The way it is currently configured does actually work (I did some testing with regard to the 4th user creating folders) due to the ACLs being inherited.
Basically, everything is working as it is, but it's just a bit of a bodge job (I think) having people using the same log-in account (albeit different short names, creating a pseudo-group).
If Finder Comments were editable by users with RW access, rather than only the file owner, it would all work delightfully. I'm really surprised that this issue hasn't been raised before, which is leading me to believe that something in the way our permissions are set up is causing the problem. I even tried giving explicit write permissions to the .DS_Store file, but it still doesn't allow people to write comments.
I did read somewhere that someone reckons that people with RW permissions (and not the file owner) can write Finder comments. Can anyone verify/de-verify (is that a word?!) this?
Thanks,
Tom
