Sending address?

Actually, if you add one of your own change addresses to your address book, it will get added to your list of receiving addresses, and then you can sign a message with it. This fact is known to almost nobody, as almost nobody ever has to actually deal with change addresses (and ordinary users never do).

Interesting.  You learn something new every day.  I'll have to try this. Thanks.

However, if the address was a change address, then you have no way of signing anything with the private key of the address as far as I know.

Nobody ever has to know what their sending address is either, especially as if you use an e-wallet, your sending address will not even belong to you. If anyone ever asks you about your sending address, they're doing something horribly wrong.

Thanks
