I have gone through all the settings to see if I can get my avatar to show up on the forum but it simply shows a default image. Any idea how I can fix it?
You set up your avatar on your Xbox - either the 360 or the XBO.
From Google:
Select the profile that you want to customize from the Home screen.
Select My profile.
Select Set gamerpic.
Select Make one with your avatar. …
Select Make a gamerpic.
Select Change background.
Select the pose that you want.
Thank you I will fire up the 360 and see if it will show up here.
