You May Need to Re-Upload your Avatar
Hey Team, on Saturday the servers were hacked and a bunch of stuff on a bunch of sites was deleted. Trevor has been working diligently to fix it all, but one thing that we don't have is avatars that were uploaded up to one month ago. So if you've uploaded or changed your avatar recently, and now see a "red X", you will need to re-upload it.
You can do this by logging in, going to the Forum, clicking the "User Control Panel" tab on the very top of the forum, and then going to Profile and "Edit Avatar".
