While the primary purpose of darthvader101 is to discuss Vader's physical condition, I don't want the focus to be so narrow that people feel restricted when writing essays/asking questions.
So, I added this to the community info page:
"What about Vader's personality?
Characterization issues can certainly be discussed, especially if they relate to physical issues in some way. (For instance, "Do you think Vader is mean because the suit is uncomfortable?") If you want to discuss why Anakin Skywalker went to the dark side, however, that's not really on topic. think_anakin would be a better place for that."
In other words, if your question/essay deals in some way with Darth Vader as a whole, both his mind and his body, it is definitely on topic. :)
