Wow, lots of people from FF.net.
I have the same name there as here ( www.fanfiction.net/~phantomsunssong ) and I have written a variety of things over time, though I'm currently working on Fullmetal Alchemist, Danny Phantom, and Pokemon (I know, laugh all you want...) fanfictions. I also have a thing for dragons, so as a result, I have both an FMA and DP fic with plots centering around them.
I also love most crossovers, even if I know little about one of the fandoms of the crossover. (That's how I got interested in FMA, haha...)

Hopefully then I can put up my own fanfiction. It's going to be a HP/FMA crossover (FF.net probably doesn't need anymore of those though). So far I've partially thought up a verrryyy basic (crappy) plot, and I know how I'm going to start, but I'm not sure what I'm going to do after that.
Yeah, there are quite a few of those. The ones with basic plots don't usually go very far, though. Try twisting it around, change things from the norm as much as you can. A majority of them place Ed in as a student. Try doing something different than that, even if it's just placing him in a different house. For example, one story I've read put Ed in Slytherin rather than Gryffindor, like most do, and it's got over a thousand reviews. Granted, there was a lot done with the plot as well to make it really good, but you get the picture. Don't be afraid to really mess with things and put the two worlds together in a way that hasn't been thought of before, either. Maybe you can bring the HP cast to Amestris for a change?
Ah, I'm probably not helping much, but anyway, I'll keep an eye out for it. I like those. ^ ^
