Martin Riddle is starting to organise tn21 online, as evidenced by the news items that have already gone out through this column.  It is interesting to look back at the tn19 webpage (https://ishr.site/d3Kt) and scroll through all the news items sent out to participants to get an insight into what goes into running such an event - even when it didn't get started!  Remember the bushfires?  Hats off to Martin and Deb.
