If you send a message to someone who is not your friend that message may be stuck in their "other" folder, depending on their settings. The only way to be sure the message goes to the intended person's correct folder is to send them a friend request prior.
Friends are requested through Facebook. You can message to potential friends your Facebook name or your Facebook associated email. Doing this via chat however is a violation of KoC TOU.
Rummage through your friends list and see if they're still on there.
Look through someone that is friends with them, they might have a picture with them tagged in it.
If you're on about 'typing a message' to someone through thte Facebook chat then you can simply start typing your message underneath the actually chat box, However if you mean you want to send another Facebook user an inbox then the simplist way is to go onto their profile and below their name there will be a link saying 'send ... a message' .. Click it! Then a box will apear with field to place a message and subject :). Hope this helps.
You can't send pictures to Facebook through text message, but you can send them through picture mail.
Nope. Unless they look through their friends all the time and notice you aren't there (Lol).
best way is to find out that person's number or email through friends or family and once you got a number or an email send a quick message saying, "hey add me on facebook, (email)." I know its not through Facebook, but it's the only way i know. good luck
a facebook cleanse is when you go through your friends list and delete a whole bunch of people. hope this helps :)
They won't get any notice of it, but if they go through their friends list they won't see you. That might give them a hint... Yes, it is very possible for your friends to determine if you deleted them from your friend list specially if they have applications that has the ability to track this records such us Facebook Friend Checker http://thesocialmediaguide.com/social_media/removed-from-friends-list-facebook Unfriend Finder http://darktips.com/find-out-who-deleted-you-in-your-friendlist-on-facebook/ Who Deleted Me http://www.youtube.com/watch?v=f5ui9zYvPb4
You can prove someone is stalking you through a false account if you have messages from the profile. You can report the false account to the Facebook support team.
You can chat to your Facebook Friends through Skype, So I think its a Good Idea!
Just because Facebook is available 24 hours a day doesn't mean that you have to be. People send messages through Facebook when it is convenient for them so you can answer the same way, when it is convenient for you.
