Arrow then guides you through setting up some message parameters. Arrow includes the ability to send messages in digest format. Some subscribers prefer getting a whole group of messages all at once instead of singly. Digest allows you to set the number of days during which messages will be collected before being sent to subscribers who request them. Arrow also has some rather basic but efficient security features.
People wanting to subscribe to a list can send a message requesting to subscribe.
To verify that the person really wants to subscribe, you can instruct Arrow during installation to require that each subscription message be confirmed. If the user respond appropriately to that message, he or she is added to the list. As another security feature, you can disallow certain users from posting altogether. After Arrow is installed, using it as a moderator is very easy. All messages from subscribers or unsubscribers that are addressed to the list stay on your ISP s server until you launch the Auto feature in Arrow.
