On a quick look, this is quite a cunning thing, although it would be more useful if one could get tafs and metars and a notam narrow route briefing by email, by specifying airport codes and a route in say the subject header of a blank email.
"Modern" pilots navigate with GPS (backed up by VOR/DME) and don't need a wind corrected plog because one is getting continuous track guidance. I have not done a w/c plog (except when required to for tests) since I got my PPL in 2001.
I see we are again getting into the "does not use the circular slide rule" = "unprepared pilot" territory which IME is a long way from what really happens out there. There are indeed pilots who take off without any preparation but that's because that's the way they are, not because they don't know how to do it. Teaching them some methodology isn't going to make them do it.
