Ms Keys is a former school teacher. She now works as a professional proofreader, working mostly with academics who don't have English as a first language.
She came up with the idea for the course in the wake of media publicity around her Grammar Vigilante campaign.
Armed with chalk, duster and a permanent marker, Ms Keys corrects the spelling, punctuation and grammar on public signs. She has since started up a Grammar Vigilantes of Aotearoa group - the Facebook group has more than 160 members.
Ms Keys said the Whanganui branch has just had its first meeting. The next one will be held at 9.30am on July 15 at Breakers - all are welcome.
FACH starts on August 16 and runs for three consecutive Wednesday evenings. To register for the course please contact CES on (06) 345 4717.
