After experimenting with gravatars and the like, the icon to the left of the "My Account" tab at the top of the screen is always a custom green avatar. I think when I post a comment, it would show that green icon too.
Also, do changes made to gravatars take a long while before being featured on my blog?
The colours of my blog http://quixoticzephyr.wordpress.com/ is pretty much at war against each other now.
The blog I need help with is quixoticzephyr.wordpress.com.
