Hi,
Following on from John's translation posted above - In the last couple of weeks the author of "Indoor = No Wind = More Fun": Harold Slit, and myself, have been working on completing a new edition with a full translation into English, combining and editing some of Harold's translation work, a little new material, John's translation (thanks for letting us use this John) and some new translation from me.
It is posted on Bram's site at: www.flyingkites.nl . Please press on the button labeled "indoor" and choose the English version (or Dutch version if you prefer).
Best wishes,
Peter
