My donation does not show up
If you've made a pledge and don't see it appear in the campaign's "Donors" list, several things can cause this to happen, and none of them are your fault:
The campaign owner has their PayPal account set to manually accept payments. This means your donation is waiting on their "approval." Only once the donation is "accepted" by the campaign owner will PayPal let us know that you've made the pledge.
You've made a donation using an 'eCheck' or other form of payment that PayPal deems must "clear" first. Only after it has cleared will PayPal let us know that you've made the pledge.
All in all, most of the time all you have to do is wait a bit, and your pledge will appear under the Donors list.
