Tewy (pronounced Teh-wee) is the name given to the Wikipediauser who joined the project in mid-2006. If you have any questions or comments, you are more than welcome to leave a note on his talk page. He will usually respond as soon as he receives the message, assuming he's not busy in real life.

The CategoryTree is a MediaWiki extension that provides a dynamic view: you can change how much you see of a category's structure as a tree. You can use it to show a category and its subcategories by putting the category name between category tree tags like this:
<categorytree>
Trees in religion
</categorytree>
The result is a category tree like the one shown to the right. Click on the triangles to expand and collapse the tree.
My day on Wikipedia begins with checking my watchlist. I review each change, add necessary comments, and revert any vandalism I come across. Occasionally I will click links to random pages and clean up articles that don't meet Wikipedia's standards, but the majority of my time is spent voting. And I don't mean for politics. My favorite spots are Featured picture candidates and Motto of the day. Here is a summary of the ideas I have suggested for others to vote on.
For your hard work over at WP:MOTTO, I hereby award you this. You create mottos (which are outstanding, btw), archive them, make improvements to them, reject/approve them, and more. Oh my gosh, don't get me started on your work at WP:FPC... Well, you understand what I'm saying (right?).
