I see on the list of upcoming features for wpbook, the ability to handle multi-author blogs. I'd love that feature! The blog I admin has several authors, and we're using wpbook lite to crosspost from the WordPress site to a closed FB group. At the moment, all items are posted as Notes, and as if they come from me. That's confusing to our users.
It would even work for us if the author was the "blog account", rather than my personal account. That may be a middle ground feature, easier to implement than true multi user support.
In any case, thanks for a great plugin, and I hope I can use multi-user publishing in the future!
