IMO...they are for CONTRACTORS to bounce things off of, to get help, show off work, sell equipment as needed. Also to help new guy's getting into the business and steer them in the proper direction so that they can help, not deter the industry as a whole. Also to allow VENDORS to show, sell, their products and help us on equipment questions, new and upcoming changes in equipment, chemicals, parts, etc. At all times it should be a place that the only dumb question is the one not asked.
