Admin and Layout Notes
Admin and Layout notes will appear on editing pages with this <!-- -->. They will not show up when an article is read, but will be visible when editing. These articulate policies such as listing things in alphabetical order, notes on what should and should not be included in a page, and other little things that are more for the editors than the readers.
Most of these are to help things run smooth. If a page has a note, follow it!
Editing Admin and Layout Notes
The policy is short and simple. Do not edit Layout or Admin notes without good reason. Typos and mistakes are fine. Deleting or changing the meaning of a note is probably not your call to make. If you're not sure, don't do it. Ask an Admin before changing a note significantly.
Deleting, editing, modifying, or otherwise messing with an Admin or Layout note on a page will result in an immediate two-week ban, with time continuing to be added with subsequent violations up to a permanent ban.
