@cwebber I'm not a techy. Last time I tried to program anything was a text based adventure on a C64 in the earliest 90s. Gave up after that. Yet I've been able to read this entire text because it was so well-written and clear, even to a language teacher with only very mild interest in networking. Thanks! I couldn't get halfway through Newbold's text.

As a linguist, though, I'm curious as to why Newbold *chooses* to use incomplete definitions: has that use been informed by crypto culture?
