Once you are able to change your profile picture (avatar), let us know about the image you have chosen.
(If you change it later too.)
To change your profile picture. Go to your profile and hover your mouse over the picture you wish to change. You should see the message "Change Picture". Click on it and upload a new picture (not too large please - 250 x 250 seems to be the best size).
Mine used to be a bit boring, but self explanatory. Now I have a Shadok avatar, which I created myself. Shadoks are cartoon characters from France, but they are also the admins on our Discord channel.
