You may not be aware that [EE] stands for "Everything Engineering." In hindsight, we probably could have chosen a better tag since EE sounds like "Electrical Engineering" to most people, but it is too late to change it now. Also, you DO know that you can choose not to receive posts with [OT] or [EE] topic tags? Just go to the mail servers web page at: http://mailman.mit.edu/mailman/listinfo/piclist sign in, and change your settings. For more information about this list please see http://www.piclist.com Further discussion about the running of the list, topic tags, what the admins are doing wrong, etc... Should be marked with an [OT].
