The comment said something along the lines of 'Aya Brea managed to convince Nomura to get a Twitter'. Googling 'Aya Brea' links to Parasite Eve stuff.

nooo problem

Above your avatar is what's called your "usertitle"
At this point you are not able to change it

The title represents your "rank" on the forums based off of post count.
its just a fun little thing we've put together
as you make more posts your usertitle will change to different names of elements and characters throughout the Kingdom Hearts saga.
Once you reach 1,000 posts your username will turn red and you will have some special user abilities (this is referred to as being a premium member)
and once you reach 3,000 posts your username will turn gray and you will have some more abilities as well as the ability to change your usertitle (this is referred to as a platinum member)

you can find out more information about this in the FAQ
