I'm pretty sure that it translates to something close to this (don't stick to literal grammar)

Hello with all!

A new TEAM has been just created, the TEAM Assassin, we are in this moment three in the TEAM and we seek gamers for Halo 2 and soon 3!
Thus if your level on the live one is other than that of a noob come to make your request for recruitment on http://assassin.roxorgamers.com
However you can always come on the site and its FORUM to take part in the activity of our site which has been just built, it would be extremely sympatic!
I forgot a very IMPORTANT thing, we recruit SERIOUS people and MOTIVEES which are lend to make drives, tournaments (because we will fairons some) and to have a good STATE OF MIND!!
Here, now if you want my gamertag on the live one for me speak it is “ridoman”!

Do not be afraid of poster!
