The WordCampEd Vancouver 2009 website was just moved from a PBWiki site to a shiny new WordPress site. It was odd not using WordPress to power the website for a WordPress-related event, but initially I thought it made more sense to just use a free, low-friction service like PBWiki.
But, now we've got a WordPress site, configured to behave kinda wiki-like. Anyone can login (either by creating an account or by using OpenID). Once logged in, you can edit any of the pages, including Sessions, Attendees, Logistics, etc... You can also create new pages (although new pages _may_ need to be "approved" before going live).
If the new site gives any grief, please let me know ASAP.
