They mean the specific plugin that allows mobs to drop money.
That aside, normally there are options that allow you to change how much each mob drops in a configuration file. If your plugin does not allow you to do this, you should probably switch to something that does.
Well i need a mob money drop plugin thats what i asked in my original post yet nobody decided to help me and thank you so what mob money drop changers are there? since iconomy doesnt let me change it i guess
The server my friend is hosting is running it on CB Ver 2070, although I'm not sure which version of EcoCreature they are using.
It seems the Bukkit team were misleading when they claimed that plugins would need to be updated to work. I myself am running a few much much older plugins (from beta version 1.6) that run as smooth as a baby's bottom with no errors whatsoever.
