David Sanchez featured a great post on the Sports Marketing 2.0 webpage that details the fact that teams are losing potential revenue/ traffic hits by not registering all of their relevant domain names.
Think about it. How many persons might misspell your domain name during a search and inevitably give up? David suggests that teams should purchase all the potential domain names for their site (which range from $1.99 to $40.00 per month) in an effort to generate more traffic and also help users find your site.
Consider having your organization pay an outside company to perform a domain audit to investigate misspellings, international domains, domain name suggestions, and more.
