Connect a channel, queue posts on a calendar, and let Signal publish on schedule.
Open SignalLink the account you post to. Signal publishes on the official API so posts come from you.
Drag drafts onto days, or let Signal spread your queue across a sensible cadence.
Skim what is scheduled. Anything you have not approved will not go out.
Signal publishes on schedule. Check the calendar any time to see what went out and what is coming.
