While teaching in game is nice, there is no way you can be everywhere at once and teach everyone who wants to learn. Even with several people in the game trying to teach, it still doesnt really cut it. The old ijji forums had a Wiki and I can see there's another one starting up here but thats not enough either.
I highly suggest AeriaGames to do what MAIET used to with K-GunZ, in that they had Styles listed on the main page with all of the techniques in plain sight for anyone who wanted it. Sooner or later people are going to want to learn Styles (unless they are dead-set on not using them like oldschool E-Stylers). Now a days everyone points people to YouTube for learning, and that works to a degree but having the information on the main site (not an outside wiki on the forums) would be the best way to go.
The problem has always been what's listed under the Controls tab as "Advanced Moves" is not even considered beginner level to GunZ players. GunZ is a deep game thanks to all of the exploited glitches, and the community has slowly been evolving in skills since the beginning. There's such a gigantic gap between the evolution of skills that what was considered advanced then is now considered basic fundamentals. New players trying to jump into GunZ will find the difficulty curve extremely-hard or may think people are hacking when they are using glitches. There is a very large amount of glitches to master in GunZ, it can be daunting when you see them all in a list, however they can be broken into levels of difficulty so people aren't overwhelmed. More importantly though, is that the players know the glitches exist and aren't left in the dark to how to perform them.
