Facebook is a social networking site that allows users to communicate with each other. The site has a Poke feature that allows users to exchange information and photos with each other. To use the Poke feature on Facebook, you first need to create an account. Once you have an account, you can access the Poke feature by clicking on the three lines in the top left corner of your Facebook screen. The first line will show your current list of friends and family members who are also Facebook users. The second line will show all of your recent posts and updates. The third line will show all of your Pokes that have been sent to you since you last logged in. To send a poke, just click on the blue button next to the post or update that you want to send out. You can also type in a message or post code to send a poke. If you don’t have any Pokes in your inbox, you can try sending one by clicking on the green button next to the post or update that you want to send out.
