Avatar & Sig: 10/10 (I don't get why people are b****ing about it being old. Your avatar and signature are supposed to reflect who you are inside. And that doesn't change every day.)

lol 9/10's and I must be a confused person in the inside cause I keep wanting to change it...

Probably (or maybe you just haven't found something that really reflects yourself yet :) )

Sig: 5/10 Great, I absolutely love it, but crashes the browser on my handheld every time a page loads where you post. (it normally has no problem with flash)

Avatar - 9/10 - It's Avatar related, and its Jake taking another big step in his ability to be closer to The People by listening at the Tree of Voices

Signature - 10/10 - These quotes are so great, I love to read them and ponder over their meaning

Avatar: 10/10 (pic of yourself)
Sig: 10/10 "Imagination will often carry us to worlds that never were..." Very powerful quote.

Avatar: 10/10. You have my respect.

Signature: 8/10. Nice pics, but try to array them more creatively.

I'm getting a new avatar (and hopefully sig) soon!

Avatar: 7/10...what is it?
Sig: 7/10 cool pic, but idk..

Ahem.
A more appropriate question would be "Who is that?", sir. :P
And that's for me to know, and you to find out. ;)
And I thought lava dragons were fasionable. :(

9/10: Epic date in history.

9/10: Also epic. But includes lots of full stops. Your grammar defies physics.
