Here's the way to get an avatar to show up on your posts.
(a) Right click on the picture of Daniel J. Travante below and choose Save As. . . (just save it to your desktop a someplace you know you can get to easily)
(b) Go into "Settings" (link on the upper left of each page I think)
(c) inside your profile (settings) you'll see a button that looks like a camera. When you click on it - you can upload the photo you saved to this site as your avatar, just path the upload to the picture you put on your desktop.
Here's a picture of my profile with yellow arrows to show you what I looked at.
“No one is born hating another person because of the color of his skin, or his background, or his religion. People must learn to hate, and if they can learn to hate, they can be taught to love, for love comes more naturally to the human heart than its opposite.”
