I have a paper that uses the article document class, in twocolumn mode. The title and the author are set within a \twocolumn[...] command. Now I need to put a footnote after the name of the first author, so that a small "1" appears next to it and the footnote (containing the e-mail of the first author) must go at the bottom of the page.

The problem is that I've discovered that \footnote, within \twocolumn, makes the small "1" appear right after the name of the first author (but not so close to it, and this is not good) but I don't find the footnote at the bottom of the page.

How can I perform this task?

As an example I put here below a small piece of code that demonstrates the problem:

\documentclass[twocolumn]{article}

\begin{document}
\twocolumn[{\centering \LARGE \textbf{Test\footnote{Test title 
      footnote} Test Test Test Test Test Test Test Test \bigskip}}]

    Test\footnote{test text footnote} Test Test Test Test Test Test Test 
    Test Test Test Test Test Test Test Test Test Test Test Test Test Test 
    Test Test Test Test Test Test Test Test Test Test Test Test Test Test 
    Test Test Test Test Test Test Test Test Test Test Test Test Test Test 
    Test Test Test Test Test Test 
\end{document}

As you could verify, the first footnote does not appear, while the footnote into the text, appears, and with the number 2.

You can use \footnotemark within the float and then \footnotetext at some point on the first page but outside the float. Alternatively if you used \thanks it is defined (in two column mode) to do exactly that. It makes a mark at the point it is used, but saves the text so that \maketitle first sets the title texts in a 2 column float and then executes all the saved \footnotetext commands from \thanks.

You might want to use the tablefootnote package, which also takes care of the right hyperlinking, if the hyperref package is used:

\documentclass[twocolumn]{article}

\usepackage{tablefootnote}

\makeatletter
\newcommand{\spewnotes}{%
\tfn@tablefootnoteprintout%
\global\let\tfn@tablefootnoteprintout\relax%
\gdef\tfn@fnt{0}%
}
\makeatother

%\usepackage{hyperref}

\begin{document}
\twocolumn[{\centering \LARGE \textbf{Test\tablefootnote{Test title 
      footnote} Test Test Test Test Test Test Test Test \bigskip}}]
\spewnotes

    Test\footnote{test text footnote} Test Test Test Test Test Test Test 
    Test Test Test Test Test Test Test Test Test Test Test Test Test Test 
    Test Test Test Test Test Test Test Test Test Test Test Test Test Test 
    Test Test Test Test Test Test Test Test Test Test Test Test Test Test 
    Test Test Test Test Test Test 
\end{document}

You just need to make sure that there is no page break between '\footnote{...}' and \spewnotes, otherwise the spewed footnotes end at the second page.
