Webdesigntuts+ has a thorough series covering Foundation 4 you might be interested in. If your a Lynda subscriber, they’ve got a couple of courses on Foundation 4, as well. There’s not a whole lot of difference between the grid in Foundation 4 and Foundation 5. Foundation 5 does add a new medium breakpoint which is great for tablets.
Man, the quality of the videos on Lynda.com always impresses me. But I don't wanna pay $25 when that's the only series I want. Wish I could just do a la carte.

Verifying email addresses is vitally important for building a high quality list. Otherwise, you can easily sign up other people for the list, they get essentially a spam email, report it as spam, and all of a sudden your list is crap because they didn't have double opt-in.
Keep double opt-in, it's necessary (and I think required in Mailchimp's case unless you use the API directly).
