There has always been a difference between formal English and colloquial speech - the change now is that young people don't recognise that difference. I believe some A-level entrants use textspeak in their papers.
Forum etiquette is to ignore mistakes in spelling and grammar, hard though it may be for the pedants amongst us - and I know we have many retired and working teachers in our number. We have had numerous threads where we have told of our pet hates (mine is 'between you and I) so this is not a new theme for us - but it is always interesting.
I don't know why everybody does not use Spellcheck, which takes only a second or two. I use it to correct my typos because I am a fast touch typist and my computer cannot always keep up with my fingers.
The mistake I notice very often is the use of 'loose' for 'lose' - I find this hard to understand as they sound very differently.
I have several dyslexics in my family and I know it has no correlation with intelligence - one of my grandsons has an MSc in marine biology and his dyslexia is so bad that he was statemented at school and given 25% extra time for his 'A'-levels.
I would hate to think that any member was inhibited in posting because they feared criticism of their use of English.
