My understanding is that C. Turner backs up the forum regularly (probably once a month). He works in the IT area as his day job, IIRC, so he pretty much knows what needs to be done. He is one of the two main administrators.
The worst that has happened to this forum is when Photobucket dropped its free support and required a $300 annual fee to use their service. Many of the photos used for reference were stored on Photobucket and now are difficult if not impossible to retrieve.
