Pointless read as no one is interested in plays - either staging them or reading them - especially in the current situation with Covid-19. I'm 56 and have been writing for 36 years - poems, plays, short stories, novels - I've read countless "how to" books, been on countless courses and done correspondence courses and it is all a waste of time so save your money. No one is interested. Unless you write for pleasure then don't bother. I still write, for my own enjoyment, but I don't even try to get work published now.
