By default we display a pre-configured set of columns for your portfolio. If you desire you can easily change the columns that are displayed in your portfolio. To do this click the Options link at the top of your portfolio and choose the Change Columns menuitem.
Clicking the Change Columns menuitem will display a list of columns that are available and a list of columns your are currently using. You can add and remove columns as well as change the order of your columns. If you want a description of a column, just click on the column in either of the lists.
When you are finished change your columns, click the Change button to save your changes and get back to your portfolio.
