How do I Boost Custom Games in Halo 3?

[Swaton1 (Runescape)]

Ive seen up to 97,000 Custom games played so i know its possible I just wanna know how to do it. BTW the gamer-tag is Souljatoytellem
That doesnt work you have to have at least 2 people in the game....

Start the game then end it. repeat if necessary
