The admins have just announced that they plan to remove the old versions of the courses listed in the title of this topic next week (on Wednesday, August 16). I’ve already voiced my opposition to this move which got very little attention. So once, again, I am stating this loud and clear to said admins in regards to the old course versions:
LEAVE THEM ALONE. I’m serious right now. I’m perfectly willing to work thru the new versions of those courses, but please leave the old versions alone! Or at least just make them accessible to users who completed them once already, like me. See the forum post below for more details:
