There has been a lot of publicity lately about the expansion of the ebook market and about the particular success of erotic writing in the ebook format. The reason is obvious - people are much happier reading erotic material on an ereader when others can't see what they are reading.
But it's a very difficult genre to write well and practise is needed. I've come across this website that enables writers to practise and develop a following. It's worth a look.
