Hi Khris, and welcome to PortlandWiki! I like what you've done so far, and List of Portland Mayors is a great addition. I hope you stick around while the wiki is still rough around the edges. If you need any assistance with anything, feel free to drop me a note on my talk page.
By the way, you can sign your comments by adding four tildes ~~~~. This automatically signs with links to your user page, user talk page (this page we're at right now), and the date and time you commented. You can customize your signature in your preferences if you wish. My signature (which is uncustomized) looks something like this: -kotra (talk) 22:13, 25 December 2009 (UTC)
