Run federal grants too?

State grants are free to browse and are not part of member fit-scoring, alerts, or the Tuesday digest — those cover federal grants. Members get every federal grant that opens fit-scored to their organization (the home page defines exactly what the board covers) — with an alert when a real match posts.
