Q&A for How to Use Facebook

Yes, everyone can see your posts, even if you are not friends.

If you're in Chat, click on a person's name and a window box will appear prompting you to type a message. If you're in Messenger, go to your Contacts and select a person. You will have a chat head open from which you can message only that person.

There should be a small, downward-pointing arrow in the upper right corner of the post. Click it, and there should be a dropdown menu. Simply click "delete."

No, that is not possible, and websites or programs that say they can are certainly scams and probably have viruses.

If it's on your Facebook wall, next to their comment on the right-hand side, hover your mouse cursor over a little 'x' and it'll say 'hide this'. Click on the little 'x' and you wont have to read their comment. If it's a private message, click on the little star-like symbol in the top-middle of the page and a drop-down menu will appear, showing a number of different options on how to hide the message or to delete or block it altogether.

Right below the comment, you can find two buttons "Like" and "Reply". Clicking on the "Reply" button opens up a new box, similar to the comment box, wherein you can type in your reply. Press Enter to post the reply.

Press the message bubble button to the right of the friend icon and select the friend you want to private message. If you have a cell phone or tablet, there is also the app Facebook Messenger that you can use.

Absolutely not, all the information on Facebook is stored in their own servers and unless you have access to those, you cannot modify the date on the materials.

Other people have their privacy settings configured so that only their friends can see their posts. Some users' posts are completely public, but the majority of Facebook users have their privacy set to "Friends Only."

They receive a notification saying you have poked them and have the option to return the action.

They can only see it if it is on the Facebook website. They can see your Facebook friends, and photos on Facebook, but they cannot see your phone information that is not connected to Facebook.

No, you wouldn't be able to due to the site's privacy policies.

Do you have ad-block? If so, you need to turn it off for the page before clicking on an ad. If not, try other browsers and see if the problem persists. Try searching up the problem and see if there's a solution online.

They can. It would be best to set your first name accordingly. So if a couple were John and Jane Smith, set your first name as John Jane or John and Jane. As for identifying who is posting comments, I think it would be wise to sign off with your name. For example, commenting on a picture of a friend: "Beautiful photo. Your new haircut is lovely. - Jane."

You can use an app called Facebook Messenger. You can download it as an app on your phone or go to Messenger.com online. You can chat with friends on Facebook itself by either clicking the message icon in the upper right corner of the screen or opening the chat menu in the lower right corner, and then selecting the person with whom you want to chat.

If you try to visit someone's profile or send them a message after they have blocked you, you will see an error message. (If you try to search for their profile, it won't appear in the search results.) This is the only way to know if someone has blocked you.
