Ok let's take the specific example: 
I am upgrading the information on Romania's main article AND then I realize that the transportation article is simply a stub. 
I copy the information to the transport from the main article that (information that I initially added MYSELF in the main article)
I realize that the main article on Romania will be trimmed down a lot 
I do not have time to trim the main article myself so I will let other ppl do it
meanwhile, the extended information is 'stored' in the more specific article about transportation
 where did I do wrong?
