By default, your event's partners are referred to as "Sponsors" in Konf's navigation bar. Your organization may have another term for these people or businesses, such as "Partners", "Patrons", or "Supporters". Luckily, you can change how Sponsors are labelled by following the below steps.
From the Navigation bar on the left hand side of the screen, click on Customize:
On this screen, among other options, you will find the "Rename sponsor(s)" field. Add the new name (this can be anything you want), then click the "Save" button at the bottom of the screen.
The new name will be added to the registration page as in the picture below.
It will also be changed in the Navigation bar, and anywhere else that Sponsors appear.
