 Please keep direct messaging to a user or a set of users to a minimum.
 Direct messages should be avoided for any technical discussions or asking for support, even if you are sure that you have involved all those who are interested or who can contribute.
-Instead, such discussions should be in a thread in an appropriate :ref:`discussion channel<slack-discussion-channels>` and support questions must be asked in an appropriate :ref:`support channel<slack-support-channels>`.
-Direct messages should be reserved for conversations on topics such as code review requests, logistics, or on other topics not directly related to work.

-- In place of amending a message, it is preferable to use strikethrough ``~text~`` to retract an idea or statement that if you post something you recognize as wrong. A corrected statement can be added next to it. This prevents surprises of seeing a notification and not finding that message on Slack. Moreover, this indicates the thought process undergone and avoids somebody else posting the same point again.
