I noticed a few people trying to change their Avatar. A recent breakage in Tea Trade meant that I rebuilt a number of systems. Right now, uploading avatars is not working – it uploads, but results in a broken image link. I’m working on this.
However, as an alternative, Gravatar is working. I use it, as do a few others, which is why my avatar is working. On Tea Trade, it is an automatic thing, associated with your email address. While I am working to fix the broken issue, Gravatar works great and is even compatible with many other websites across the web. Just make sure the email address you use with Tea Trade is the same one you set up your Gravatar with.
Noting @lazyliteratus, @roswellstrange and @jackie on this.
Let me know if you have any questions.
