Aims to focus on aspects of the menace of spam, or unsolicited messages by e‐mail, are treated, especially a service designed to stop spam at or near its source. A TV documentary asserting that global warming is not due to human activity is reviewed and shown to be unsound. A search facility that contributes to charity is introduced, as well as sources of health advice in periodic newsletters.
The paper reviews developments on the internet, especially those of general cybernetic interest.
Combating spam by the means described can be effective. The view that global warming is due to human activity is not seriously challenged, though there is room for difference of opinion about the imminence of catastrophe.
The menace of spam can be mitigated by the means described. There can be little doubt that global warming is largely due to human activity.
It is hoped this is a valuable periodic review.
