no offence but why not make it millitary like and forget the whole money thing it seems to make something so simply complicated just like have 10 clans then all battle it out to protect right? oh well I'm just saying I hope you dont make it complicated :d
I propose some sort of Java/Flash interface that clan leaders can access and carry moves on that accordingly. A simple graphical interface would give us a visual sense of a map, action buttons, wealth, buildings...etc.
I have some expertise in Java coding so I could help anyone in coding certain things. I do not have enough experience to lead an app project though. So anyone feel free to step up. Or maybe even talk to some Dev's and see what they can do for us =p
