Hi Graeme,
No worries about the quick posts -- we're happy to help if we can.
Files in the files browser are access-protected as they are actually private system files: all submission file versions, etc. The public dir isn't accessible by default, but you can symlink it to your files directory location and it will appear in the Files Browser (
viewtopic.php?f=8&t=3980&start=0 for a full discussion).
There's been ongoing discussion on developing a 'workspaces' type of plugin that would allow users to upload files to the system and to allow access per role (or optionally to allow for full access). I haven't submitted a feature request for this yet, and it's likely a fair bit of work as authentication and access rights would be a concern. Any thoughts you might have on the issue would be appreciated!
Cheers,
James
