(adsbygoogle = window.adsbygoogle || []).push({}); Thats right the join in progress when u press triangle on ur XMB is NOT disabled. It was confirmed by David Vonderhaar on twitter

For those who say give me proof here it is:
You must login or register to view this content.

so this clearly means its not disabled, u just cant use that feature in some matches

This is not for ps3, at least not for mw2 :mad:

Join session doesnt really bother me but when annoying people join and messs things up :confused:
