By uploading a photo directly from the app.
For sure! That's too boring to create an account with Gravatar !
And when you upload it doesn't work... Pfff...
Definitely planned! We want to quickly get rid of Gravatar (and if the upload does not work, try clearing your app cache for now)
You can now change your avatar directly from the app! Just go to tribeez.com or update your mobile app :)
