Welcome message
Hello, and welcome to Wikibooks!

Here are some tips to help you get started:
 * To learn the wiki-markup-language syntax, see Help:Editing.
 * Make sure to sign your posts and comments with four tildes, like this: &#126;&#126;&#126;&#126;
 * There is a box at the top of the edit window (if javascript is enabled on your browser) that will insert it too (looks like part of a signature). This will let others know who left it, and make it easy to reply back to you.
 * Remember to conduct any editing experiments in the sandbox.
 * You can tell the community something about yourself in your userpage.
 * You can get to this page by clicking the tab at the top of the page labeled with your registered username.
 * Wikibooks is a collection of open-source textbooks. (What is Wikibooks).
 * If you are a Wikipedian, see Wikibooks for Wikipedians for a primer on how things work here (it's a little different).
 * If you want to base your work here on materials from Wikipedia, please use WB:RFI.
 * If you're an instructor and plan on using Wikibooks for a class project, see Guidelines for class projects
 * Please say hello at the Reading Room with any questions or ideas.
 * Eventually, you might want to read the Manual of Style and Policies and Guidelines.
 * Help us by participating in policy and guideline creation.
 * Please take a look at Naming policy before starting a new book.
 * Remember to maintain a Neutral point of view.
 * Explore, be bold in editing pages, and have fun!

You will find more resources in Community Portal. If you want to ask a question, visit the Study help desk, the Reading Room, IRC channel or ask me personally on my talk page. For site news, see the Bulletin board. It might be a good idea to add that page to your "watchlist" so that you can see when any new information is posted there. You can do that by clicking the tab labeled "watch" at the top of the page.

Good luck! --Panic (talk) 06:12, 5 September 2009 (UTC)

Your tutorial on arrows
Hello,

I just noticed the the arrows tutorial you wrote three years ago, and I am shocked at how it has been overlooked for so long. In my opinion, it is a perfect replacement for the unfinshed Haskell/Arrows. I will incorporate it into the book, as soon as I finish some cleanup work in the monad chapters and refresh my memory on arrows (probably by using your tutorial!). Thanks a lot!
