As my nym would suggest, I tend to take the work of others as a starting point, though the directions I develop them may not be what they intended. Feedback is always welcome, not only positive but especially negative. If something doesn't work for you, tell me about it. How else can I improve?
On a final note, I'm not at all proprietary about my stories. Feel free to steal plot points, ideas, or characters. I'm always curious to see what others would do with the same material. (Another chance to learn!) It'd be nice if you dropped me a note, though, should you do so.
