Lead Sources
On every lead capture for an account creation form, there is a "how did you hear about us?" question that is mandatory. This enables you to capture the lead source and report on it later to work out your best marketing channels to focus on.
You have complete control over your lead sources and you can edit this list at any time.
To mange your lead sources:
Navigate to Leads
Click + Add Lead
From the "Select Source" dropdown click Create Lead Source
You can also remove existing lead sources but please not they will not be removed from existing leads in your system.
