Groups of hackers are very difficult to maintain because they can turn against each others very easily.
Nevertheless we will study the group / clan suggestion and implement a working system in the near future, but for now we are monitoring how people can get along in the game without any group features. You are still free to help each other, as long as you don't use multi-accounts to gang on someone and such, you can gang on targets with your ingame friends sure, it's no problem.
Until then, we can use the ingame message system to form temporary clans / alliances with your own free forum.
Refreshing so Titam remembers that he said he review the idea in the near future approx 8-9 months ago.
