Oh yeah! I do have an FF.net account! 8DOver here!
I've written quite a handful for FMA. A couple of Cardcaptor Sakura fics, and one for Tsubasa Chronicle and one for xxxHolic (but the two are "intertwined", much like TRC and Holic really are. XD)
The CLAMP ones are old, so ignore them. My writing back then sucks. XD
The FMA ones are quite new, haha. I have two drabble/one-shot collections. I've completed one of them ("Permission to Sympathize, Sir!") and the other one ("A Day in Our Life"), I have no plan of completing any time soon. XD Oh, and I mainly write Royai or anything involving the Roy-tachi. As much as I like EdWin, I just can't write them. I attempted to, once, and it's there. (It's a two-shot for April Fools. XD)
My main story is "A Day in Our Life", the one-shot/drabble collection that I'm currently focused on. It's got a little bit of everything in it, I guess. I've written fluff, angst, crack, and a whole lot of other stuff I can't exactly classify. XD Mostly the stories revolve around Royai and/or the Roy-tachi. I don't follow any specific set of themes for that one. I just write whenever I get an idea. Sometimes I use the Royai Themes as prompts to set my ideas in motion. Oh, and I've used themes from other fandoms too (actually just Romeo x Juliet. XD)
