Source. If quote, person; if paper, link or send PDF to maru.the.mareck on Discord or u/mareck_ on Reddit (note: I do not use the Reddit "chat" feature. DM me.). Kindly provide page number, also.
The astute reader will note that it is, in fact, the intention that one sends me a (link to a) PDF after "never having DM'd [me] before" (unless, of course, you have DM'd me before), as is implied by the directions given. Thank you!
