My opinion is tainted by hindsight now, but the "five minutes" page as is now would probably be sufficient :) I guess it really depends on the target demographic (experienced programmers or total newbies, et al). I would love to see more use of Haskell as the first "learn to program" language (going on a tangent here, sorry).

I updated the install page with notes for these issues: http://www.yesodweb.com/page/five-minutes
Let us know if you think that would have solved your problems. If not, we can link to a more in depth wiki page.

I believe Neil said the HaskellNet package wasn't compiling on ghc7 but that it shouldn't be hard to fix and that he might do it. This package should allow you to send email on Windows.

Can you add a Wiki page[1] with your install experiences? I'll link to
it from the "five minutes" page.

As for the sendmail issue: I'm actually going to need a backend for
Amazon SES for sending email, so I'd like to get that written. (Any
volunteers? Aristid already has a great aws package that should do
most of the heavy lifting.[2]) There's also haskellnet which uses
SMTP, but I haven't used it.
