If the assembly wants to consider a main motion later, what can a member move to do?

When the assembly wants to consider a main motion at a later time, moving to "Postpone Indefinitely" is the appropriate action, as it effectively sets the main motion aside without a direct vote on it. This motion is often used to avoid a debate on the merits of the main motion at that particular time. By opting to postpone indefinitely, members can choose to revisit the issue later when they feel more prepared, or when the circumstances are more favorable for discussion. This is particularly useful if there isn't enough information currently available or if there is a desire to focus on other matters before addressing this specific motion.

In contrast, placing a motion on the table temporarily suspends discussion on that motion but doesn't preclude further consideration; rather, it must be taken back up at a later point. Extending debate does not delay the motion; instead, it allows for more discussion on the current topic. Withdrawing the motion means the member is asking to eliminate the motion altogether from consideration, rather than postponing it for later. Thus, postponing indefinitely is the definitive option for delaying consideration of the main motion while keeping the possibility of revisiting it open in the future.
