9. Profile information - personal information Many people don't list all of their hobbies- instead list the ones you're interested in attracting friends for. If you've got a 'guilty pleasure' remember that people may be able to access your information, even before you add them, so you may not want to publish that. The boxes in this section are entirely optional. 10.Contact information One of the boxes you can fill in is 'contact information'. Be aware that depending on your security settings (see security and privacy) you may then place your ID out in the 'open' which can open you up to spam or bot contact. 11. Profile information - Network If you're interested in chatting with, or meeting up with people in your region, you can add where you life and join that 'uber - group'. Some require email addresses or other information that 'proves' affiliation, but Facebook has recently improved that interface, so it works very well. Your network affiliation is listed on your profile, unless you change the security settings (see security and privacy) 12.Profile information - friends As we'll explain later, you can keep those that you've added from appearing in your search, but your friends list is always visible. Be careful when adding 'controversial' people in your life, as it's very easy for other friends to use your list to find others to add - the only exception to this is if you add someone with extremely tight security settings 13. Profile information relationships Facebook allows the listing of relationships in your profile - but until the person you're in a relationship confirms it; you will only be listed as in a relationship. Otherwise you will be tagged as 'in a relationship' but not with whom.
