you change your avatar way too often >=P. Every time I see a new avatar I think a new person on the forums, then I see it's you again.
Don't hate me, it is a personality thing, people who spent their first lives in Graphic design forums tend to be like me.
I kid you not.
I'm alright with avatar changes.
It's the name changes that bugs me =/.
Cool people keep their names as it is
I like Ahoge-fairy myself, but Manhattan fairy was to go with the occasion you know?
Name changes are also a frequency in graphic forums to dictate what sort of design mood they are in.
In my case, I used to use "Menos" when I do dark stuff, and I use "Omega" when I do bright stuff. "Omni" is used when I do ordinary stuff, while "devilicious" is for the sexy stuff (NSFW usually)
Call it a habit if you will, but each forum has its own special demographical behavior.
