I am currently using EssentialsX series (excluding geoip and xxmp, for I am not quite sure what they are for) and Residence plugin by Zrips (Vault installed). I am not sure what economy system Residence uses under such circumstance, for I didn't install an economy plugin. I guess it shares the economy system with the essentialX plugins. Is this true? Also, if it is the case, is there a way that I can make all the residence making operations free (not costing money in the economy system) ?
