FACEBOOK - Avoid unwanted guests
HOW TO MAKE FACEBOOK PRIVATE
Log into your Facebook account and click
on 'Privacy' in the top right. In the 'Profile' section, click on 'Edit
Settings'.
You can now choose who can view you profile. You can either allow all your
friends and all the people in your network to view your profile, some of your
friends and the people in your network, or just your friends. Select one of
these options from the
drop down menu next to 'Profile'.
If you scroll further down, you can select who can view different features on
your profile. You can select options for features such as the Wall (this is
where all your comments from your
friends are posted) so that only you can view them.
Once you have made all your changes, click on 'Save'
