Subscriptions

Our homepage shows messages from all topics and user groups by default, and all message types (except NASTF SIRs and Resources). Alternatively, viewing your subscriptions stream will show only messages posted in types, topics, user groups to which you've subscribed, using your settings below. In addition, your notification settings can be adjusted to turn notifications on or off for these subscriptions.
A message's type defines what kinds of information it can include, and how we show it to others.

Include in Message Stream & Notifications

* This type is not normally shown in the homepage message streams, nor does it trigger notifications, unless you subscribe to it "Always."
