As a heads-up, there is serious talk of limiting downloads of the free e-zine to registered users to enable better tracking for use in advertising sales. Apparently, that will likely start in January, although on-line reading would supposedly not be affected. Since registering is at no cost (and gives access to some additional material), it's probably a good idea to do so.
BTW, I've no link to the publication other than an interest in seeing it remain free.
