Con Donations are buggy
The form for donations automatically changes to a credit card information form as soon as any amount of money is entered in the form field for donation amount. In addition to the process being jarring, it also does not allow you to finish entering the amount and there's no way to change the amount after the form has changed. Also, the site says they limit donations to $100 USD, but higher amounts can be entered with no indication that they wouldn't go through.
