SFWA stands for "Science Fiction & Fantasy Writers of America"*. It's a professional writer's association: members have to qualify. For a long time, the qualifications were approximately "sold three short stories to qualifying markets" (broadly speaking, I believe that means "ones that pay at least $0.05 per word", though it's more arcane than that) or "sold at least one novel for a professional advance" (presently defined as $3000). Recently, courtesy of the efforts of haikujagur and others, SFWA updated the criteria to include "or received $3000 in royalties in the first year of publication of a book", so that the growing number of indie-published authors would have a path to membership, and to keep SFWA relevant in a changing world.
A Rational Arrangement qualified me for membership, which is on the long list of things RA has done that I never expected it to. (Nice job, book! Keep up the good work.)
I applied for membership, half-expecting that it would turn out I somehow misunderstood the self-pub criterion. But no, they let me in! I am an actual member of SFWA. Just as if I were a real author!
There are various perks to being a member; the ones most relevant to me are the quarterly Bulletin, which includes honey badger cartoons by Ursula Vernon and MCA Hogarth, and the members-only forum, which always sounds neat when I hear people talking about it.
I think part of me thought that joining would lessen the imposter-syndrome voice in my head, but this was clearly ridiculous. I am merely upgrading the quality of the identity I'm falsely assuming. Thanks, voice. You're very annoying.
Anyway, inner voices aside, this is a Cool Thing and joining SFWA has been on my list of life goals for many years. So: Yay! I did it! \o/
* Yes, I know there's not enough Fs for that to be the right acronym. I am pretty sure the "& Fantasy" was added later. They've been around for a while.
