Did you know that you can precisely control which columns a user can view in Watch My Domains SED v4 ?
You can specify an access level (from 0-8) to every domain data column in Watch My Domains SED v4. You can also specify an access level to every user. Columns with level-0 can be accessed by all users, but columns with higher access levels can only be accessed by users with the same or higher access levels.
All administrative users have a default access level of 24, which means they can access all columns. It is possible to use the API to expand the access levels to 32 instead of the default 0-8 supported by the user administration interface.
