You should add Crackshot support for Kills, Deaths, Friendly Fire, Vitals and etc.

Also a customisable lang file would be awesome!

If you are still interested, answer with more details.

If you do decide to do this, dont use CrackShot, Quality Armory took over and is much better.

To decide, I'm gonna need more details. Like how will the hook work? What does it mean by supporting vitals? Does Crackshot increases a player's life?

I don't use either at present, I just wanted to make sure that if any support was added it wasn't for CrackShot but Quality Amory.
We are tempted in the future though as were a Pirate Server and flintlocks might be cool!
