It was my understanding we would be able to pick an alternate advanced class for our characters. To check this out, I logged into the test server and created a character, but I can't figure out how to switch to an alternate advanced class. I made him a Jedi Knight (for the story), but want to use the Consular abilities. To this end, I intended to use the Sage class.

How do I do that? I can't find any way to select an alternate advanced class.

As an aside, how do I copy a character to the test server from the live server?
