On Halo 3 in-game, you must click on the video, select share with friend... then find the person's name in your friends list.
When you remove someone from your Xbox Live friends list, you are removed from their friends list and they are removed from yours.
You invite your friends to either firefight or campain. You can also join friends on your friends list if there games are open and they havent started the match yet. As for matchmaking the game doesnt have.
Well you click on the friends' list you want to delete or highlight it and press DELETE
on your main menu there should be a thing that says friends online just move your right stick over and click on a name it will then give you a list of options. hope i helped!
Yes there are people on the A list. They normally have a lot of friends and all the moshlings.
No
Did you set it to local? Or maybe invite only. Try making it open, or invite only. Then go to your friends list and invite them.
Click on them and send a friend request
You can go on their profile, scroll down, and on the left, there should be an unfriend button. You can also click on your friends list on your profile and there is an "x" =delete
Sadly there is no way to get your friends back. It is completely useless to call or mail Xbox on this concern. They keep no records of deleted or preferred friends. All you can do is try and remember people on your friends list, look at their friends list and hope that they added your previous friends
