Does it ever happen that people (e.g. on forums like this one) get together to communally write an anthology. E.g. of short stories on a theme (horror, mystery, whatever?) It seems to me that there would be a number of advantages. As a group, the authors could critique and edit each others' work. In terms of the mechanics of preparing ebooks for publication, there would be many hands make light work. And if there were (e.g.) ten authors, then there would be ten circles of family and friends to form the initial readership of the anthology.
