Make sure you have ticked the ‘Include me in the list of pledgers’ option when checking out your order.
If you've already placed the order, you can by going by going to Orders and clicking on ‘See Pledge Details’ next to the appropriate project. The tick box will be underneath your items on the order review page.
Also, check that your Personal Profile is visible and complete, otherwise there will be no name to display in the list of pledgers. Don’t forget to upload a photo!
