If you are using Internet Explorer and you are trying to donate using the PayPal button, you may receive a "Fatal failure" message. You need to adjust your privacy settings to allow PayPal's cookies. PayPal's security is ironclad, so rest assured that no damage will result from this.

In Internet Explorer, just go to Tools -> Internet Options and click on the "Privacy" tab. Then lower your settings to "Low."

Adjust this setting back to your preferred setting when you're done, if you like.

Thank you for your support.
