Thanks, I'll try it out. So far I ended up not using the special command \title at all. Just create a section \begin{center} ... \end{center} to contain the title/author. It is ugly but it at least works.
I have one more question though. Is there a way to fine tune font size other than using \scriptsize and \footnotesize, etc.? I ask this because it appears that I need a font right between the above mentioned two, judging from the sample file sent to me from a journal.
Page Layout ⇒ reduce empty space btw title and top margin
