Spivak - Calculus on Manifolds, Comments and Errata

Back to:
[My personal website],
[OSU (work) website].

Some of these were found by my students, so thanks, though I didn't keep track of who told me about what. I also didn't manage to mark down some issues from the beginning of the book (I marked it down but can't find it), so don't think there are no comments on the first part, I just lost them or forgot them.
