@Ellri: I absolutely love horror and sci-fi. I haven't swayed too far away from medieval fantasy in a long while, so it's difficult to give an idea of genre. But I do know I almost always manage to get sucked into criminal plot lines. If I had to do a shot in the dark, I'd say sci-fi and fantasy are what I get into the most. 

As for your second question, I'm admittedly a bit confused. If you mean post length, I usually stick with 1-5 paragraphs. If you mean time I've been comfortable with my writing, I'd go with sometime in high school (the last 3-6 years or so).
