I have created a blog website at
careerdemo.com and installed WordPress to run it.
When a person signs up, they get an email from the address
firstname.lastname@example.org (this is, I guess, a default setting in WordPress).
I want to change that, so that e-mails come from my own address,
email@example.com. (So any new user will get e-mails from my own e-mail address,
firstname.lastname@example.org.) How do I customize my FROM e-mail address?
