You can move the articles of a source to a higher or lower position in the list, and you can delete sources from the list.
Choose Open, and then choose Options > Manage sources. This opens a list of the current sources used in Finance.
At this point you can perform moves and deletes as many times as needed.
Moving is a four-step task. Scroll to a source, and choose Options > Move. Scroll to move the source to its new position, and choose OK to confirm the new position.
To delete a source, scroll to it and choose Remove. This removes the check mark from the source.
Choose Add to re-add erroneously removed sources. Note that deleting a source from Finance does not delete it from any other service.
The final step is to save the new list of sources. Choose Options > Save.
