upload at gravatar
Upload your avatar inside the digi dojo
Note: Your Gravatar (if you have one activated) is displayed automatically. If you upload locally, your avatar will display ONLY at The Digi Dojo. And, if you have a Gravatar, uploading locally will cause your locally uploaded avatar to be displayed (so it affects The Digi Dojo, but not your account at Gravatar.com)
upload your PROFILE PICTURE at gravatar.com
A Gravatar is a Globally Recognized Avatar. You upload it and create your profile just once, and then when you participate in any Gravatar-enabled site, your Gravatar image will automatically follow you there.
If you already have this, your Gravatar should be displayed automatically.
In other words: Go to EN.GRAVATAR.COM, sign up once and upload your picture. It'll be activated in The Digi Dojo and any other site that has Gravatar activated.
