Ok great! Yes I believe my permission were:

Me -> write only
Staff -> write only
Everyone -> No Access

Plus I checked the 'locked' radio button.

I think I can be assured that nothing was shared as I never really fiddled with adding more folders to be shared plus with the lock on it I don't think Limewire could get to it anyways. The only way it could get to it would be if Limewire didn't have to be open to share files because I would occasionally unlock and open the folder to add new files.

I don't have the folder anymore or Limewire, but I do have a backup of it on an old Time Machine hard drive. Just to be sure I'll check around in that to make sure that the settings were never set to share the saved folder (don't think I ever changed that but who knows) and also check the permissions of the saved folder as I'm not 100% sure they were the above permissions but I do remember typing in password to open it. Thanks for your help!
