Welcome to the new Edmonton RASC Website

You may have noticed that the Edmonton RASC website has changed. We have migrated to WordPress and changed the site so it displays well on any screen, from desktop to tablet to phone. All of the familiar content is still here but there are a few new features, including our Twitter feed, a searchable website, and Stardust as both a newsletter and a blog. I hope you like the new site.
