Errors and omissions

Things move on. Accuracy at the time of writing is no guarantee of accuracy at the time of reading.

Links to other websites

Pages elsewhere are revised on their owners' schedules, not this one's. The destination of a link can drift away from the reason it was added.

Keeping this current

Should any of it change, the revised notice takes effect once it is on this page.
