::Ok, then. ) Yesterday I was a bit tired. About bot BD and Lifetime there was a discussion. Making a resume: BD is useful for adding yob/yod categories to articles. but in the hand it may be confusing for in-experienced users (I am keeping a report with example in the talk page I linked above), it confuses programms (such as HotCat, AWB) and bots (for example my Yobot) and probably DEFAULTSORT has to be separated from it. I made an effort to orphan BD but until now we got stuck in two problems: AWB seems to not be subsituting correctly (or I am doing it wrong -anyway, I have reported this and a fix is pending) and some people like it. It was clear form the different discussions that if yob/yod categories already exist then they have to remain untouched. Some editors noted, that changing them with BD is like removing white space, since this offers nothing new to the article. I hope this time I was more clear about the subject. ). Have a nice day. Cheers,
