I do not know how it works exactly with blue guys, but I have two maps in Drafting Room. there are several guys who posted there, but each one has his notices, opinions.
did anybody think about something as Map Tutors? they would not be only blue guys, but some skilled guys who will sorted maps in Drafting Room and each one will have 2-3 maps which he will tutoring and his advices will lead mapmaker (less skilled or new one) to Stamp and Main Foundry Workshop.
I wrote this, becasue I have realy some problems in my maps. I try to follow advices, but they are sometimes incongruity... therefore I think when there will be one Tutor he will has the main voice which advice should be implemnted and which one no.
just my five cents here
