The original donate page is way too long. There's some elements on the page that don't need to be there. The fax element is not needed since hardly anyone uses the fax machine. There's no need to put your name down twice. Also a lot personal info isnt needed for example, your address, zipcode, state and town etc..
This donation should just have your name, and amount you want to donate. maybe your number or email for confirmation but other than that, there shouldnt be that much going into it. In the link below it even says that less is more requading the number of fields.
