Thanks for clearing the air, tsuwm and Of Troy:

When I post something "from Dr. Bill", such as "mugs", it is entirely Dr. Bill's. I don't consider it my responsibility to read it too closely or to edit. That is Dr. Bill's own responsibility and he is highly principled about what he posts, as we all know from long experience.

If the search results in one of Dr. Bill's posts are search results which I obtained on his behalf, it is my practice to say so. Of course, I am responsible for my own search results but only for those results, not for the subject of the post or its message.

Whew! I hope that clears the air from our end as well. :)
