As we are now launched, we've been added to the list of Stack Exchange sites at the bottom of all SE pages (scroll down there now to see what I'm referring to, I can wait!). Unfortunately, the link is just "scifi", there's no mention of fantasy. We are not just the sci-fi site, we are sci-fi + fantasy, and I think that link should include fantasy as well.
It's "scifi & fantasy" now.
(Providing an answer, since Jin hasn't, so that it can be accepted so that community doesn't bump this question).
(Or this can be deleted if someone adds status-completed).
There's precedent for the abbreviation at the bottom not being the same as the subdomain (like gamedev.stackexchange.com - called game development) so I think it should be 'scifi-fantasy'
Should be, "■ spec-fi" then. To save space.
