Good morning! I haven't discovered a way to add another journal page, but my students create an ongoing journal that covers the entire school year.
I suggest that students date each journal entry. When a student wants to add a new entry, he positions his cursor at the end of his last entry, taps the Enter key twice, adds the current date, and begins typing. That way a student's newest entry is always at the bottom of the journal field which makes it possible for me to see that entry while adding my feedback, and the student's journal is in chronological order. Works great for us.
For example:
2/23/07 This was my first journal entry.
2/26/07 This is my second journal entry.
