I want to change my username.  

I don't know how I came up with RedFlamer37 but I guess it's because of my favorite color, element and number.  I remember wanting to comment on Oetori's story so much so I made an account.  I never thought of wanting to write here or spending so much time here.  My username even became sort of a joke when some friends learned about it.  Anyway, I wnat to change it.  I am impulsive and I don't want to waste my karma points.  

I thought of some so please help me choose.    

1. BluePurple 
2. purple
3. bubbles
4. happyface
5. happy
6. mars
7. virus
8. three
9. thirty-seven

Some of them are taken but with different capitals so I am hoping that they're still up for grabs.  Watcha think?
