This is sort of the thread I am looking for, I think.
Marketing and my planned attempts are as follows.
There are very few groups on Facebook actually allow writers to shout out, but I found one that I will post to - science fiction writers and those who would be - membership is 1.1k, so limited. Does anyone know of other FB groups that might be of use.
There are quite a few science fiction book groups on FB, but these don't allow promotion on FB at least. I have joined another forum (needs must, sorry!) with the aim of shouting out, and I guess it can't do any harm. Does anyone know of useful forums for this type of self promotion?
Finally just to be clear, SFF is and always has been my only writing forum that I engage in, simply because it's the most friendly and supportive - respect to the Mods for achieving this.
