There is a difference between the RoWP Template and the Ro (and other language templates).
RoWP is a template intented to show that the information posted in Familypedia has been taken from the Romanian version of Wikipedia. This could happen, because there was no article in English language Wikipedia, because the article in the English language wikipedia was incomplete or incorrect or for any other reasons. It does not imply that the article in Familypedia is a translation of the Romanian article, but just that the information in the Romanian article was used in Familypedia. They can be used in Familtypedia articles written in whatever language.
The language templates indicate exactly the opposite. They are supposed to be used in Familypedia articles writen in other languages to show that these articles have been translated from English to Romanian (or German, or French or any other language.Afil 20:57, April 8, 2011 (UTC)
