User wants to know how to send campaigns and convert the people that respond to those campaigns into leads.
You don't send out campaigns to make leads and prospects in CORE; they must already exist within the system. You need to attach them to campaigns and email them individually. After they respond to the campaigns, you can mark them as Responded in the Recipients tab of the Campaigns detail view. To make things easier, you can open the Leads or Prospects screen in another tab, and go down the list of people to follow up with the ones marked as Responded. Currently, there isn't a way to do this in a batch, so it must be done individually.
