Well, the one-post new member just happened to be researching pressure cookers because her exploded last night.

Cammy – Don’t let the big dawgs scare you off, their bark is loud, but harmless.  Glad to hear there was no injuries (cept for the kitchen)  kitchens need to be replaced every so often [;)]
 
Actually they are offesnsive and often scare off perfectly reasonable new posters. Many are simply bullies.
 

Did you do an autopsy on the cooker?  wsa the pressure relief valve blocked or clogged??
