Yep first I had to download the scout version of kaw or any other free version ( I think). Then u should have a new "clan" button on your home screen. Press the clan button and the type in : knights of the fire emblem. Once you apply I believe xioxas has to approve you again. I'm still waiting on approval right now. That's all I know. Hope it helped.
All clan members plz use the new clan button to reapply back into the clan. Watson posted directions on how to do this a few posts above.
