Tagging
If these pages are not intended as open edit pages while the classes are ongoing, could they be all marked with a {{308inprogress}} tag? Can be adapted from {{305inprogress}}.
This is for human editors and my bot, which will refrain from editing anything marked with a template containing the string "inprogress".
If they're intended to be open edit, then ignore my comment - thanks! --Chriswaterguy
