make it or play it？

i am not good at English... it seems that there's different between 'post' and 'lay out'?

if u mean 'upload to workshop', u can throw your maps in a mod (maybe should be in the dir 'maps'), and upload like a mod.
if u have some questions, as a reference, maybe u can find the way in my mod 'Expanding Mission'. That mod is a map mod.
