There are 4 options available under the "access settings" at the bottom of the “Post a new entry” page.
Using these options you can change the overall level of access to your journal.
(Please note that the access settings of recent posts will not be changed - only for your current journal).
The 4 access setting options are as follows:
Public : All internet users, even non-Lang-8 users, will be able to search for and view your entries via Internet search engines.
Share with all Lang-8 users : Only registered Lang-8 users will be able to view your entries.
Share with My Friends only ： Only users that are your friends on Lang-8 will be able to view your entries.
Private - Just Me : No one besides you can view your entry.
