Change mandatory fields

When registering as donor, all but a few fields are mandatory. Is it possible to change which are mandatory?
And secondly, is it possible to reduce the amount of fields, e.g. only name, email and phone number?

Thanks for the nice extension!

Hi Clemens,
You can open tool: Manage Custom Fields at Backend of Joom Donation, opening fields to modify. In field modification form, you can select No in option: Required. Thus, at frontend side, that field will not required. By the way, in Joom Donation, there are 2 core mandatory fields, they are: Last Name and Email
Those fields must be shown in Donation form because the payment gateways need those value to process online payment.
Thanks
