I support Ben Webster's position on this: the MathOverflow question and answer posts are not appropriate for asking about a subject as "too localized" as resolving the title of an article being completed.
However, there is the MathOverflow user page. I think many things which are not allowed in Q and A posts are allowed on user pages. In particular to MathOverflow, opinions, links, promotional material, requests to review papers, and other items are (or should be) permitted. This is not to say a user should go rogue and commit all sorts of anti-community behaviours on ones own user page; it is to say that (I believe that) fewer restrictions should apply to user page content than to Q and A content.
Further, an occasional comment or brief statement in a post WHERE IT IS RELEVANT AND APPROPRIATE that links to the appropriate section of the user page should be permitted. For example, I think it acceptable that Jose add something to the question like "For an example of what I need, see here on my user page", which would link to a section which might have a list of titles, or another link off the site to the paper, or whatever. Similarly, it would be bad on my part to edit his question to link to my user page, but I think it would be acceptable for me to leave a comment on his question to say "Me Too, here's my link to my problem.", and offer people to check out my user page.
The point is that there should be low impact ways to ask for help, and I believe (in moderation) some commentary and links to user pages can be made low impact and improve the community.
