==School threat and your phone call== 
 As a former school district employee and member of a family with lots of teachers and a superintendent in the family, I just want to assure you of two things.  One ~ you did the right thing.  Two ~ they won't come looking for you.  For one, they can't trace phone calls like that and wouldn't if you called to explain things as a mature adult.  Two, whether the secretary you spoke with or not knows what Wikipedia is, it's likely the principal does.  Wikipedia is on the watchlist of areas to keep track of and monitor for some schools, just as myspace and vainspace are.  You did the right thing and you shouldn't worry about it.  As a parent of a teen, believe me, you can never be too safe.  A kid threatened our school last year via myspace, turned out that his father had a lot of guns and he was looking up how to build a bomb on the internet.  Better safe than sorry.
