I am a bit surprised you do not just create a single thread for authors to publish their own work. Fairly standard practice on a lot of reading forums.
Keeps all the 'spam' in one place, keeps a lot of people revisiting and also...well, it's tough out there for debut authors you know!
Thrillers mainly, but I do read all sorts. I like historical fiction and non-fiction books on cooking, gardening and fishing all have a place on my shelves.
I also write, but I have read that mentioning this is strictly banned on here.
