I have been contributing with high quality material to Wikipedia for the past five years, and am well aware about its WP:OR policies. If you did not agree with my usage of the CN-tag or formulation of the disputed paragraph, I invited you for a debate at the talkpage of the article. Now you instead respond by posting me a warning about potential edit-war, which I consider to be very unpolite. I already agreed with you that we need to find a source for the unsourced part of the paragraph, but argued it was best to keep it temporarily as part of the article with a CN-tag, in order to invite for a collaborative work for any wikipedia editor to help finding the needed source. Wikipedia:Citation needed, proof this is an instrument we are allowed temporarily to use at Wikipedia - until we succeed finding the needed additional reference for the material (and if this is not the case - you are allowed to remove it after 1 month). Best regards,
