I am checking the program for the notes issue, being viewable by normal members, and from what I see, in order to a note to be shown, the member has to be able to view the "View XYZ Warnings" link as well.

That means that depending on your settings:

1) The post is not made by a mod, smod or admin, while the user viewing the post is either a mod, smod or admin (when not using the hierarchical schema)
2) The post is made by someone who is not a mod/smod/admin, and the user is an smod/mod/admin, or the post is made by a mod and the user is an smod/admin, or finally if the user is an admin and the post hasn't been made by another admin.

I can see no way that a regular user can see a note, if the changes made in functions_showthread.php are correct. Please verify these changes, and if you still have issues please come back giving me some details of the post and the user, as well as your settings (if you are using hierarchical or not).
