Yeah. I agree.Yeah, that did suck. And not even formal explanation.
Back in the early 1990's I was sysop for the Atlanta Macintosh Users Group and set up 2 different bulletin boards.
On the switchover to the new board in 1996 we had a great relationship with the BBS provider and we would hash out problems by phone and online to solve problems and make upgrades. They were always responsive and maintained an excellent two-way relationship.
I wonder if XenForo customer support gave any feedback or assistance to MO. Data loss to this extent is very bothersome. Was the provider at fault or did the customer drop the ball? What can they do to avoid this in the future or prepare for recovery? Lots of holes in the story right now...
