''Please don't change the name of reference definitions unless you also change it in all of the reference calls. Doing so breaks the references.'' Meters (talk) 00:49, 4 December 2020 (UTC)
 * And if you are going to change reference names, please do so properly. You cannot use a space in a reference name unless you enclose the name in quotes. Meters (talk) 00:53, 4 December 2020 (UTC)
