Mount Tahoma Trails Association is more correctly an organization vice a company so a ".org" suffix would be more appropriate than a ".com" suffix for the domain name.
Rick Burleigh, the webmaster for the official MTTA website added registration for http://skimtta.org. He also set up the URL to redirect all traffic from that domain to the existing http://skimtta.com URL.
AND because "skimtta" is confusing for some folks (like me) (what is a "skimtta"?), and because Mount Tahoma Trails aren't just for skiing, Rick also added registration for http://mounttahomatrails.org and set it up for all traffic from that URL to be redirected to the official http://skimtta.com URL.
What this means is that you can get to Mount Tahoma's official website via any of these URLs:
