Just received an email from Photobucket. Here is a partial quote from it.
Now it's time to move over to the all-new Photobucket because this existing site is going away soon. Don't worry, your photos will be on the new Photobucket experience.
They say that we don't have to worry that they will take good care of everything and I hope that they do BUT
Sometimes things don't go as planned so I would suggest that if you don't already have a backup copy of any photo elsewhere from the Photobucket site NOW
would be a good time to make that backup.
You all know how that works, If you have a backup you don't need it. If you don't have a backup that's when you are going to need it.
This is not meant to alarm anyone but only help you being safe if Photobucket has a problem while doing the changeover. I would imagine that they will also have a backup plan B incase plan A fails.
