+This expectation is to be announced to all participants at the start of the

+public portion of the meeting after this announcement is interpreted as consent to the

+
+For the private portion of the meeting, the TSC chair ensures that someone
+produces a summary of the discussions, gets it reviewed by the attendees,
+and shares it to all the TSC members once approved by the attendees via a
+private discussion channel such as the TSC private mailing list. The summary
+may be made public if there is consensus within the TSC and the non-TSC

+Recording the private portion of a meeting or maintaining or publishing a

+All discussions made during meetings are considered provisional, receiving no

+the TSC endorsing that action.
+
+If a quorum of TSC voting members is present, it is possible to call for an
+explicit vote, and take the vote immediately if there are no objections. The
+decision is considered confirmed once the rest of the TSC voting members have
+been informed and no objection for taking that vote has been raised in 48 hours.
+To clarify, TSC voting members can object to the vote taking place during the
+meeting, but not to the vote itself.
+
+For discussions outside of meetings, the TSC uses
+[the TSC issue tracker](https://github.com/nodejs/TSC/issues) for public
+issues, and the private TSC email list for private matters. The process for
+public issues in the issue tracker is:
 
 * A TSC member opens an issue explaining the proposal/issue and @-mentions
   @nodejs/tsc.
 * The proposal passes if, after 72 hours, there are two or more TSC voting
   member approvals and no TSC voting member opposition.
-* If there is an extended impasse, a TSC member may make a motion for a vote.
