Reader Debbie Kennett was kind enough to remind me of the work of this organization. Founded in 1979, the Guild of One-Name Studies is now home to more than 7,850 surname studies registered by over 2,300 people. Debbie's own work on the Cruse/Cruwys family can be found there, and provides a wonderful example of how a study can create a great location for those researching family names to come together.
This website should be one of the first stops for anyone researching their family surname, or registering a new name. Thanks Debbie, for a great reminder.
