Recently the HPANWO blogs, especially HPANWO Voice, has been targeted by a spam campaign that is very irritating and disruptive. Therefore I am changing commenting policy. From now on comments will be held for admin approval before publication in the comments box. I apologize to all genuine regular commenters, like Laurence, Carl Truthseeker and Xylomet, for the inconvenience this will cause you; but there's no other way to control this plague of spam. Alternatively you could join the HPANWO Forum, see links column.
