I never learned RAf writing and decorum in letters and memo's and I have often been frustrated over the problem of many 'people' reading something of potentially massive importance and then completely disregarding the points made to make petty remarks on grammar and spelling?
Believe it or not, more than 99.999% of the world does not know what is in the RAF/MOD manual of writing stuff and has not passed a UK based GCSE A level in English - but still manage to get into jobs where report writing is needed.
