Phone Number Required (even though there is a phone number)

Delete this snippet from:
plugins/wp-donate/includes/donate-display.php

if (form.phone.value == "") {
	alert("Please enter your phone");
	form.phone.focus();
	return;
}

Now the plugin will no longer check to make sure a phone number was provided. You probably also want to remove the asterisk from next to the phone entry field, so that it looks like so:

<tr>
	<td class="title_cell">Phone</td>
	<td class="field_cell">
		<input type="text" class="inputbox" name="phone" value="" size="15" />
	</td>
</tr>

Since the phone number is no longer required.

Hope this helps!
