Eliminate the page number on the Latex title page

"LATEX will automatically number pages, but often you don't want a page number on the title page. To eliminate the page number on the first page, put \thispagestyle{empty} before the \maketitle. "

This paragraph is copied from http://stuff.mit.edu/afs/sipb.mit.edu/project/www/latex/guide/node9.html. However, if you follow this guide, the page number will still stand there, never leave with the wind. The correct way is that put \thispagestyle{empty} after the \maketitle. When using \ chapter, the same rule should be obeyed.

By the way, don't use \thank with \maketitle, there is a bug that Latex will produce an additional (mostly blank) page in the output.
