I have a drip email Campaign - Many Emails and Wait times between the email sends - The Campaign is driven from an Actionable List. If I add members to the Actionable List after the Campaign has been activated, will they start the Journey at the beginning, where it currently is at, or not at all?

Is the campaign set to run on a recurring schedule?
Whether newly added members enter the flow depends on the campaign schedule. If it is a one-time send and that scheduled run has already occurred, adding members to the Actionable List afterward will not cause them to enter the flow.
If it is running on a recurring schedule, newly added members can enter at the next scheduled run.
They will not join the flow at the point where existing members currently are. There is no functionality for members to enter partway through the flow—they always enter from the beginning when the flow runs.
