Even digi-dummies (as me) can use it in a split second.
However, I need some color in the box. So I tried a skin as offered in: http://themeover.com/plugin-styles/
But the WP-engine did not recognize the zip to upload. BUmmer!
As for the troubles some here have with receiving mails: they enter your box in a second! And that's what it's all about. So I don't understand why some have troubles and others none...
