I've seen 4 people from XG, then Reflex sent a message, I was interested and joined, From SYN Animosity then SYN New Dynasty then XDC Designs. I was actually going to leave XG, but now I'm glad I can make a mark, have a purpose, and be of help to the community. Can't say I didn't do anything.
I joined this past December when MW3 was new. I had a very good buddy that had joined and he kept asking me to join the community. I decided to join and have been happy ever since.
