Are you just looking for a report of the existing accounts?

If so try this:
Login with the Host account.
Add the Report module to a page.
Use this SQL after changing the portalID from 2 to the number of the portal you want to report:
Select
  U.UserID "UserID",
  U.Username "UserName",
  U.DisplayName "Name",
  P1.PropertyValue "Telephone",
  P2.PropertyValue "Cellphone",
  AM.Email "EMail",
  UP.Authorised "Authorized"
from
  aspnet_Membership as AM with (nolock)
  join aspnet_Users as AU with (nolock) on AM.UserID = AU.UserID
  join Users as U  with (nolock) on U.UserName = AU.Username
  join UserPortals  as UP with (nolock) on U.UserID = UP.UserID and UP.PortalID = 2
  left join UserProfile as P1 with (nolock) on U.UserID = P1.UserID and P1.PropertyDefinitionID = (select PropertyDefinitionID from ProfilePropertyDefinition where PortalID = UP.PortalID and PropertyName = 'Telephone')
  left join UserProfile as P2 with (nolock) on U.UserID = P3.UserID and P3.PropertyDefinitionID = (select PropertyDefinitionID from ProfilePropertyDefinition where PortalID = UP.PortalID and PropertyName = 'Cell')
where 
  AM.ApplicationID = (select ApplicationID from dbo.aspnet_Applications where ApplicationName = 'DotNetNuke')
  and UP.IsDeleted  = 'False'
  and U.IsSuperUser = 'False'
  and not exists (select UR.UserID from UserRoles as UR where UR.UserId = U.UserID and UR.RoleID in (select R.RoleID from Roles as R where R.PortalID = UP.PortalID and R.RoleName = 'Administrators'))
order by
  U.LastName,
  U.FirstName,
  U.Username

Thanks,
