if you click on the tab from your chess.com page that says MY HOME and choose Friends, from there you should see an option that says Invite Friends. :)
invite friend to play

Well, in live chess you simply select the tab marked friends and it will show you which friends are playing live chess at that moment. Then you can click a friend's name and challenge.
For online chess, you can send a challenge whenever you want and when you friend gets online they will be able to accept the challenge.

When I follow the steps to invite someone for Live Chess, I am led to a page that says Online Chess, which I don't want. Don't see any options to invite a friend for Live Chess, when they too are in Live Chess. Any help is appreciated. Thanks!
