This forum is no different to any other. Respect your fellow poster/member.
Having said that these forums are not moderated within an inch of their life and a certain looseness is allowed.
Suppliers are allowed to mention their products details, spec and prices if requested by a poster.
Launching into a long spiel about how their product is superior to other brands will probably be considered spam though and will be shut down and most likely deleted.
Play nice everybody!
