Thanks are due to Mandy for her help researching the poetry, Don Thompson for the suggestion of a Lunar Image of the Month, Chris for his numerous excellent suggestions and relentless encouragement, and the many correspondents who have given me ideas and support.
Inconstant Moon is dedicated to my wife, Melanie, for her limitless love and tolerance, and for squeezing my hand so hard while we waited for the results at the UK Web Awards ceremony. I have sometimes foolishly promised her the Moon... this site is not really what either of us had in mind!
