Good evening,
I'm trying to learn how to implement Haskell on a web site.
I've got the O'Reilly book: "Developing Web Applications with Haskell and
Yesod".
I'd appreciate some guidance in regard to this.
I'm having a bit of a problem getting the helloWorld.hs app up and running on
Yesod.
Thank you

Well, what's your problem? Saying that you have one doesn't help us help
you ;). Paste in any relevant error messages that you can't figure out
and post your system information.
PS: Next time create a new thread instead of replying to an existing,
irrelevant thread.
