I spend more time on FA, where you'll find me at Treppan, as well as on F-List, where you'll most likely find me as that Hellhound I mentioned, though I have other characters. Admittedly, most of my time on there is spent people-watching or socializing.
Eventually I'll use Inkbunny more often, but most of the people I'm watching are more active on FA. Inkbunny has some pretty nice features, though, so I'm hoping for more migration. I guess I could spam pictures of my hellhound or something, though, to fill up the gallery.
