But Arthur, its a waste of time. This forum is owned and maintained by a supply company who aren't going to change the rules whatever the outcome.
Leave it alone, things are pretty lax on here anyway and Express have been tolerent of most abuses. We still get to hear of all the new releases in the machine and chemical world. Advertising isn't banned, but when its rammed down your throat month after month everyone gets annoyed. I think the advertising by one company on here has been counter-productive anyway and has actually lost them customers.
There are 'special' places for manufacturers to advertise on the other boards, but they have to PAY to use them, and hardly anyone reads them anyway!!
