The Diogenes Club
(I am writing this on behalf of Mycroft Holmes, who could not be bothered to take the effort himself.)
The Diogenes Club is a group for those, who, from shyness or from misanthropy, have no wish for the company of their fellows, yet are not averse to comfortable chairs and the latest books; in short, it is for the most unsociable and unclubable persons on Librarything.
No talking is, under any circumstances, allowed, and thus there is no discussion forum.
I have myself found it a very soothing atmosphere.
