Jesus, what the hell happened here? Anyway, ignoring recent events: Yes, I think you should write your new Fanfic. Not only am I sure it will be entertaining, but as someone (Mr Evil?) stated earlier, if you get bored, blockish (yay, new word!) or stuck on a story you can always go and write your other one. Go for it. However, I don't think you should sink back into three simultaneous stories.
