Umbrella Bureau, the official TBU GTAO Crew.
The crew is set to invite only, and everyone in TBU will get a automatic pass into the crew. Once in I will promote you to the rank to allow recruiting. This basically means that anyone in TBU will be able to invite others into the Umbrella Bureau.
In case its needed, I have already created a forum section for GTAO and the Umbrella Bureau.
Anyone can request a invite from the site or from in game.
