Below the area where you type your entry, there is a dropdown list that allows you to select the security level you want to assign that entry. You may choose from Public, Private, Friends, and Custom. The Custom option will not appear if you have not defined any custom friends groups (http://www.insanejournal.com/support/faqbrowse.bml?faqid=62).
PUBLIC: Anyone, whether logged in or not, may read entries that are marked Public.
PRIVATE: Only the user who posts an entry marked Private can read that entry. If you are logged in and viewing the friends page of someone who lists you as a friend, your private entries will appear on that page when you are viewing it, because you have access to them, but no one else who views the friends page of your friend will see your private posts.
The authentication is done with cookies. If you're logged in (http://www.insanejournal.com/login.bml) and you have access to see a certain post, it will appear with a textual or graphic indicator of its security level.
USING THE WEB INTERFACE:
In the drop down listing of security levels, on the bottom you should see "Custom...". Choosing this option will make a set of checkboxes appear directly below the scroll box, one for each set of friends groups you have defined. When posting with custom security, you may choose one, some, or all of the currently defined friends groups.
Note that if you post to more than one custom friends group, anyone who is in any selected group will see the entry, not just those in all the selected groups.
KNOWN ISSUES If you are unable to see the drop down menu for selecting a custom filter on the update page, it is likely that the issue is related to the autofill function in Firefox.
The issue of the autofill function not working correctly with the site has already been noted, and the site administrator is already working on coming up with a solution that does not compromise security but still enables the function to work. However, such development will take time, and we seek your understanding and patience until then.
The solutions to regain the ability to select a custom filter are: - to post as private to ensure that the security of your post is not compromised and then edit the post to select the filter as this is not affected; - to disable autofill for InsaneJournal; - to login once using a fake account (eg. user, with password as the password) as this will store the entry so that the autofill function will not automatically work, and allow the site to work correctly for you.
USING A DOWNLOADED CLIENT:
Many clients available for download include the ability to set security levels for journal entries. For more information on your preferred client, consult its documentation or its menu options. See http://www.livejournal.com/support/faqbrowse.bml?faqid=158 for information on downloading a client. (Note: Not all LiveJournal clients are supported by InsaneJournal).
While you can restrict who is allowed to read your journal, it is not possible to know exactly who is visiting your journal. You can, however, add a hit counter provided by a third party. To find a source for the counter, you will need to locate one that does not include the use of a scripting language (For more information about this restriction, please see http://www.insanejournal.com/support/faqbrowse.bml?faqid=42).
