First, allow me to start off by welcoming you to the wiki. It's nice to have more people joining and wanting to help out. Second, I see you've done some edits to the Nepstation Millionep article here. While I'm happy to see you're eager to do things around here I'm going to have to undo your edit (again) because the article was fine as is. The Nepstation Program does not start until Chapter 2 of the game and not Chapter 1; thus, I will be putting it back the way it was. I'm sure you were only trying to help so don't take offense to this,
Not at all. The prologue is basically introducing Neptune and the Hyperdimension. The Prologue ends when Neptune gets dragged into the Ultradimension. Chapter 1 starts when Neptune meets Plutia and the alternate Noire. This chapter ends with Neptune getting her powers back. At the end of the chapter, they announce that they will be start Nepstation in the next chapter which is chapter 2. If you don't believe me you can look on the Lastation's Rise to Fame page and see the Side Events section. For further confirmation, you can also go to the Nepedia in your game, check the Timeline at that same Chapter and see it for yourself. Trust me.. I've recently started playing the game for the fourth time again from the very beginning so I know what I'm talking about.
P.S. You were right about the Chapter 9 being listed twice, so I fixed that.
