Guy:
On that subject: If there is a way to know about new authors in the library, I haven't yet found it. It would be nice to know when new authors are added so that we can be sure to sample their work, welcome them, and encourage their further participation with comments. Perhaps {Latest} {Authors} ?
There is no actual way of determining new authors at present ... but now that we're going to update Facebook whenever we have a new author (and Twitter as well) we can just as easily bung a post on the Noticeboard section of our forums and alert people about it.
