he means inviting your friends to the private match you're in without using steam .

its not implemented yet so you cant play with other people. hopefully NTA will in the future like in mw2

Maybe implemented in later revisions. Don't expect things to be quick, coding takes time, and there are quite a lot of people that still can't even play...
