Hi BoH  thanks for your prompt response  I read through translation of your History of the Oil Tanker article and its quite nice  With respect to the oil tanker article Im sure you understand that I have to edit everything thats added while its in the goodarticle review stage  As for the number of citations I know that the English Wikipedia is much more picky about citations than others  The Rule of Thumb is Not every statement in an article needs a citation but if in doubt provide one  Cheers
