I haven't been a member very long on MR, and was skulking long before that as I became more and more interested in ebooks. So I could be wrong, but it does seem that the book pushing has been increasing.
On the other hand I have gotten some very good books from people on MR. Not only do I enjoy some of the books, but it gives me great pleasure
buying from new writers.
I would like VERY much to see a "Hay, Look At My New Book" forum. And it needs to be broken in to genres. If you want, let people vote on the genres.
I'll cast the first vote. I want a "Vampire and Mummy Romance" section. Can't get enough of those books.
Back to work.
If you look at the bottom of nomesque's post you'll see something that I would allow in any writers signature. With one proviso. Only two or three lines promoting books.
Any rules should be "at the discretion/judgment of the Mods". Loopholes not allowed. I don't want someone saying "But it doesn't say I can't do that!"
