I have Photoshop Elements. I started going through some recommended tutorials from this forum. Lesson 1 - The Pen Tool

Oh. Apparently Photoshop Elements doesn't have the pen tool. Off to a great start...

Pen tool aside, before I get too far into Photoshop elements, is elements even the right software? Do I need Photoshop ______ (whatever full is called) to take advantage of this software in the context of map making?
