I too am growing VERY weary of sorting through the NON-PD posts. Many of us do NOT have the luxury of time to do this. If those of you who routinely post NON-PD posts would simply begin their subject with the words "NON-PD", it would be a simple matter for those of us who don't have the time to wade through all of the NON-PD posts to filter them out. I would hate to unscribe, but is reaching that point for me. Charles Black American Society of Lighting Designers
