The history of English word usage. Fascinating for anyone who loves words but essential for anyone trying to vaguely keep things accurate in historical fiction. Also a little addictive.
I've belonged to this for more than ten years. It is a huge community of people who write, at all levels of experience. Mostly Americans, but many from all around the English-speaking world. There is a free course you can do to see if you like it, before paying to join. If you join, there are many interest groups, self-moderated. I belong to one focusing on literary short story writing, invitation only, full at the moment and not taking members. There are groups writing every kind of genre you can think of. The standard varies hugely from group to group, and from course to course.
That's grand, thanks. I Americanized (sic) my blog recently (to help me get a job in California) and found it a lot more painful than I had expected. It seems 30-odd years of training makes habits hard to break.
Site listing huge number of writing opportunities. Used to be free but recently became necessary to pay to join. Weighted towards the US, but does list Australian opportunities, such as anthologies. Basically world wide publishing opportunities.
