Advertising principles

• Ads are always labelled “Advertisement” and never appear as member content.
• Placement is by equipment type, industry or discussion forum — advertisers do not receive member personal data.
• Technical discussions stay independent of advertisers and OEMs.
• Job vacancies, recruitment and staffing services are not accepted as advertising.
