[1] Kowethas an Yeth Kernewek recognises the validity of all forms of revived Cornish, and membership is open to all, although most of the Kowethas' publications have been in Kernewek Kemmyn and the Standard Written Form (Middle).
Kowethas an Yeth Kernewek respects the rights of its members to use whichever form of Cornish they choose, although its written business is conducted in SWF (M) because that is the form used by the majority of its members.
Every month since late 1976 the society publishes a Cornish Language magazine called An Gannas which consists of articles, stories, news, comment and puzzles.
The society also produces tea-towels, mugs, car stickers, pens, cards, T-shirts and other items for sale, all displaying the Cornish language.
Recent years has seen some events conducted by videoconferencing, extending the reach of the Kowethas to overseas members.
