Hi Logan and welcome, if you want to change your avatar picture, click “My Profile” in the User Control Panel, then, in the User Profile click “Change Avatar”.
I’ve seen that you like the blueprints, could you tell us something about you and ATLA?… when have you watched the series for the first time, your preferred character, etc.
You’ll find that people here is very friendly.

Aang: “I’m just one kid.”
