About Site Owners (Windows SharePoint Services 2.0)
When you create a site, it automatically lists you as the site owner. Depending on the configuration of the site, you might also be required to specify a secondary owner for the site. Confirmation notifications are sent automatically to the site owner and to the secondary owner, if one exists.
The owner and secondary owner of a site are members of the Administrator site group for their site. They are also identified separately in the configuration database as site owners. You can change this owner flag only by using the Manage Site Collection Owners page in Central Administration or by using the siteowner operation with Stsadm.exe.
Note
If you remove an owner from the Administrator site group for the site, the owner retains the owner flag in the database and can still perform Web site administrative tasks.
