My name is Zach Dennison, and I joined Wikipedia on May 12, 2005. I am always using Wikipedia as a resource, yet I am fairly inactive when it comes to editing and creating articles. My biggest interest is in computers. I can write batch, HTML, and PHP files, and I can write in wiki markup. Most of my article contributions are to correct typos or add a small amount of content to an article.
The Reference desk is for questions about life, the universe, and everything (other than about Wikipedia). It's a virtual version of the reference desk at a library. Wikipedians are very knowledgeable, and if they don't know the answer, they can probably find it pretty quickly.
