mAsterdam and I already dealt with this question some years ago. I think that the question is one of the wiki links, UP and DOWN, which refer to the infinitesimals. If people want to make new up and down links in the future, we can deal with that at the time.

Ah, I think I see what you mean. :-)

Well, my attitude is, if it ain't broke, don't fix it. However, if UP had been made an alias of the Up infinitesimal page, I would not have objected. And that is more flexible than renaming.
