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.
“Each day holds a surprise. But only if we expect it can we see, hear, or feel it when it comes to us. Let's not be afraid to receive each day's surprise, whether it comes to us as sorrow or as joy. It will open a new place in our hearts, a place where we can welcome new friends and celebrate more fully our shared humanity.”
