I have added a new user (SPUser) to the matching SPWeb object and have
also added this SPUser to the SiteGroups collection within a webpart.
I have tried to set this new SPUser as the owner of the SPSite object,
however, I received and error when I tried this. The error is "the
user must be a member of the site group". I have tried the about with
impersonation as well with the same results. Is there something else
I must do to this SPUser before he/she can become the "Owner" of the
SPSite?
