thanks, will do. Also why not also do this for all platforms? Steam, 3ds Xbox Live?
I created a steam group years ago and no one joined it, then I deleted it

You can't make groups on 3ds/wiiu, but there is a thread for people sharing their username/friendcodes.
I don't even know if xbox live has a similar community thing that ps just launched
AWX is mostly playstation users, and this makes it easier to set-up party chat or join specific multiplayer matches without adding people to your friends list.
