I've noticed some forum titles (Is so emo, is Fierce) that I can't see on the achievement lists. How do you get them? Ping me, please.

The 'Emo' title is acquired by achieving the 'Cheer Up, Kiddo!' achievement, and the 'Fierce' title is acquired by achieving 'Shoulda put a ring on it'. They are both wardrobe achievements :)

Ohhhh, I didn't see that. Thank you(:

You're very welcome :D
