Wow, I got just peachy news this morning.
I am enrolled in Digital Design 1st hour at school. We make websites, and save them in folders, in each of our own accounts that are saved on the school's server.
Somehow though, when I had somewhere between 15 and 20 sites (we save each one in a folder) when I left the class to go to 2nd hour Friday, I open the folder this morning where all of these sites are stored on my login, and there were only 7 there. The 2 sites I was working on Friday disappeared.
Just now though (8:25 AM EDT), I got the files back after my teacher called the school's tech department. That just wasted at least 30 minutes of my time.
