There will be no such. Everything by joining will go IC,And only IC.
In Real Life,you do not send the gang leader an unknow massage with informations about you.
Joining Will be Simple.
You will stay at the hood,show how you RP,and earn respect from Leader.
Day by Day,you may have chances to join Varrio.
You can Also Forum PM me saying that you are interested in joining the Gang,but not spamming.
