Forum:How do I join a posse

I keep getting requests to join someones posse when playing the multiplayer RD. I can't figure out how to accept. The help notification says to press "select" and something... there is also an email icon on the screen. WTF
 * I have no idea what you're talking about, are you trying to get help with a spesific game or something. I'd recommend you ask on the wiki for that game - as we don't know what you're talking about -- Random Time  09:54, July 19, 2010 (UTC)
 * Best to check out the Red Dead Wiki for that. Mark  ( talk ) 12:23, July 19, 2010 (UTC)
