Lead sources help you to identify where enquiries have come from. For example if you run a series of magazine adverts and you have an influx of calls that all quote that they found you in the given ad then its useful to be able to flag up these calls so that you can see how much business that particular ad brought in for you.
To create a custom lead source follow the steps below:

Locate and click the Update Lead List button

Create a new lead type

If you ever need to delete your custom lead, click on “My Profile” in the main menu and then click on the Admin tab and then Update Lead List button.
In the lead type management window that opens, select the name of the lead type you want to delete from the “Delete Lead Type” dropdown and once selected, click on the Delete button. Note: Once deleted this cannot be undone!
