Thank you! This website is a bit confusing lol or maybe its just that im new on here. But thank you ladys your comments were a huge help ;)
Welcome! If you are on your phone, like Charletta said, you have to be on the "Full Site" which you scroll alll the way to the bottom of the page (can be any page your on If I remember correctly) and the option will be there. Once you're on the full page, click on the person's name you would like to add and It'll take you to their profile. On the top right hand side of their profile, there will be a few options with "add a friend" as one of them. It will send out an Invitation which they will approve or deny the request. To comment on other posts, you juss click the post name and at the bottom It'll say "Post a comment" then hit send. =]
If you are on your phine scroll to the bottom of the page and click full site
