Meetings Tag Definition: Relates to the overall Meetings program and everything produced by the Meetings Department.  Additional meeting specific tags (e.g. aas222) are used to categorize items for individual meetings.


  • Items produced by other departments for a specific meeting do not contain the general Meetings tag. They are categoriezed within their subject area (e.g. Press, Policy, Public Outreach) plus they contain the specific meeting tag (e.g. aas222).
  • Members may subscribe to the main Meetings category to receive notifications for ALL meetings OR they may subscribe to individual meetings using the specific meeting number tags.
