''Wikia is converting all of our URLs to pretty URLs. While we usually see a simple URL structure (like /wiki/PageName) when viewing an article page, editing a page or viewing its history would use a complex structure (like /index.php?title=PageName&action=edit) instead. Now, simple URL structures will also apply to editing, history, and similar URLs (so you'll now see /wiki/Pagename?action=edit). The old URL style will still work.''

Really nice. Good idea guys! :)
