240px wide forms may be fine for the odd mailer form on a sidebar or two, but they are useless for an administrative backend. ;) Should they not change in size based on the type of preset you are using? Or better yet the user gets the option of setting the width during the wizzard process?
Some of those look not bad, but the 240px width is pretty unuseable for most of my purposes.
Just my 2c I guess.
