Though been discussed in the past believe it would be a good idea from this point system idea. Sure alot of coding will be required , but perhaps this could be something to look up in the future . Suggest using the search function for topics , but cut you some slack from the fact it's posted in the right area , plus your idea isn't too impossible to do.
Anyway Mods won't be required considering already have too many mods as it is. Hell we even made a mod for taunts. In the near future maybe , but for now Neji doesn't need any.
