I've come finally to the point, where I give up Because I don't want create my own SuburbsDistributions.lua, I decide to take the standard version and edit the internal names of the rooms after it. In the MappingGuide from Thuztor, he mentioned the SuburbsDistributions.lua is under "media/lua/items", but this folder ("Items") don't exist. I find only a SuburbsDistributions.lua under "media/lua/servers/items" but, there are very few rooms to choose from, so I think this one is not the right one.
