I guess this really is an adult site now Answered
Last week I had a couple days off school, so a friend and I went to visit a teacher at my old high school. One of my Ibles came up in conversation, so I borrowed a computer to pull it up. Guess what?
My senior year of high school Ibles had no restrictions. In the last year and a half Instructables has been reclassified as Adult. As a result, nobody in the Topeka school district can access Instructables.
Hmmmm, I wonder why they would think Ibles contained adult content, which might not be appropriate for the elementary school students? Such a mystery...
