so we can drink tea and talk shyte!!! 
  you've got the instructing lark sorted then....... as 'chief' instructor, cough, choke, I will be talking the most sheeite and in true chiefy type fashion, doing the least amount of work....I think it's called delegation.... or possibly learning & development as it's called nowadays although there is no budget for development anymore, just a link to a website or 'sametime' active learning sessions, maybe instructors should follow this lead and just tell people to read twist of the wrist...
