There is a Discord for the Library, found at “https:// discord (dot) (as in the symbol dot) (as in a period) gg/HvnQvQvn6u” – this is by far the most reliable method of contacting the entity known as Elliott if for any reason you should desire to do so.
To contact Elliott through slower and less reliable means, send an email to elliottthomasstaude@gmail.com. To facilitate better responses, please include “Thomas Generalized Recountings Library” or some variation thereof in the subject; a reply may not be guaranteed otherwise. Apologies if spam filters clothesline your emails, message identification is doing better but is still far from perfect.
