Jim, it looks like you were using photobucket.com to store your profile picture for use as an avatar on the LCT website. I noticed that Ngaire and others also must have been using Photobucket to store their profile pictures because their profile pictures have been replaced with the message fromPhotobucket. For some reason, the URL to Photobucket is no longer valid. I don't remember but do you have your profile picture in your signature? If so, that would explain why you are seeing the message from Photobucket in your signature now.
If I'm correct, choosing a different avatar in the "edit profile" section should get rid of the Photobucket message.
