Welcome message for new users
It will be nice that upon entering a team, a welcome message is displayed to that user. Message can be composed on the Team Settings or perhaps in the console.
In the message an admin can point out custom slash commands or any new feature that needs to be highlighted.
User can save the message (just like any other) for future reference is desired.
