We have a separate (hidden) forum for discussing group tactics, builds, etc. This is hidden to public view for obvious reasons. If you're in CC and don't see it, it's because I haven't flagged you for access. Message me in game (or just ask via XFire), and I'll add you to the list of people who see it.
Please do *not* just say it non-XFire fac chat. I'm often in all or planet, and there's a good chance I won't see it.
