Client modification is a touchy subject Malaka, you're actually lucky I taught you, the only reason I did was because I'd heard about Leo's interest in your ability's, so I figured it was best if you could literally see how your models fare once in game. All those tools I sent you and the like are also not official tools, so if the tools broke the game clients, they're not supported, and the MODer would have to reinstall, hopefully after they managed to back up their MOD's that worked. This would be an added nuisance to the staff, and could potentially cause them to change the rules on MOD'ing. Hence why in the past, i refused to make a guide on it.
which is why I'm not giving out random info and said i'd ask Leonis, but i pretty much knew that it wasn't something that would be allowed =P but its good that you clear things up, sorry everyone, no guide =P
