You may need to access the My Fundraisers page to manage your prospects plan. When you select the Prospects tab in Altru, the My Fundraiser link is missing from your options.
In order to see the My Fundraiser page, you will need to ensure you have the Prospect Manager or Prospect Research System Role. A System Role Administrator can follow the steps in this article to assign you one of these roles. Once you have been assigned a new system role, you will need to log out and log back in to Altru.
