The little bits of text under users names are called "Custom Titles". You get these when you have been a member for 8 months.
You may post in other people's Usernotes after you have been registered for 3 months.
You may get a name change after 6 months, but you have to go through Kawaii Ryűkishi to get it.

thank you, all fixed...

Why didnt i think of that on my own?
