Compliance with the POM is mandatory for all members of the 185th so you will need to read the new version whether you have been a member for 6 years or 6 weeks.
Your attention is drawn specifically to changes in the Requirements for Membership (especially broadband connection), Terms of Service, Disciplinary Procedure, authorised TS abbreviations that you will need to add to your callsign if you hold an appointment in the 185th and TS Keybindings.
