If I want to question the substance of an Article in

able to go to an editorĀ¹s personal information page and get a sense that

contact them with questions. Every, reputable reference work has this.
Every registered user has a page where they can be contacted with
questions. Mine, for example, can be found at
http://en.wikipedia.org/wiki/User_talk:Gurch . Users are also permitted
to set up personal information pages, though these have a wide variety
of uses; mine is more a collection of navigational links for my own use
than information about me. See
http://en.wikipedia.org/wiki/User:Gurch .
Anonymous users can be contacted with questions in the same way, but
since many of them share IP addresses and/or change IP addresses
frequently, and having added information may not even check the site
again for months, they may never see your question.
If you want to question the substance of a particular article, though,
it's best to use the article's discussion page rather than any
particular user's discussion page. The part of the article that you wish
to comment on may have been put together by dozens of different users,
and singling out one isn't always the best way to get feedback.
