If you have joined recently and are still stuck with the faceless man as your avatar, or if you are one of those who like to change their avatars frequently, rejoice!
I believe we've fixed the bug that was preventing you from uploading your avatar. You should now be able to upload a file and crop it up close to your satisfaction. To get started, just click the "My Account" link at the top-right of this page, and use the links next to your avatar.
The fix was ready yesterday, but I kept running into another error. Today, it's not occurring, so I'm tentatively announcing the fix to the world.
If you see any other errors, please don't hesitate to contact us at firstname.lastname@example.org.
