I went to edit a question and saw it was possible to modify the site that the question was asked on. Knowing that this was impossible, I attempted to "move" my question from Meta Stack Overflow to Stack Overflow. On submit, I got a cryptic error message "only questions can be edited with this method". I'm assuming the message is directly from the API since you can't move the question that easily.
So can the site picker become a text label when editing a question? Or if it's decided that is poor UI design, can the error message be worded better allowing users to understand what they did wrong?
