Forum Moderators: open
I and my fellow moderators hope that you will like this place. It is like a "University of Search Engine Optimization and Webmaster Techniques", with an enormous amount to read - at present more than 25.000 posts.
While it certainly seems logical to ask a question about spiders in the Spider Forum, it could be that none of the people who know the answer have seen it. May I suggest that you try to post it again in the discussion about German search engines [webmasterworld.com]. Quite a few German SEO-specialists keep an eye on that discussion and they might know the answer.
While in the European forum, please take a moment to view the charter [webmasterworld.com], where you will find information about the European forum. Because of its special fact finding nature, it has more than 40 continuously ongoing discussions - one for each country. In order to view them all, you will need to set the list box at the bottom of the forum menu page to "Show All Post". Or just click here [webmasterworld.com].
You will find more information about the Europe forum in the charter [webmasterworld.com]and in the Moderator's chat room [webmasterworld.com].
