General ⇒ Package{authblk} and command \affil

[akcays]

I seem to have a problem with the package {authblk} on my Ubuntu 10 machine. When I use the command \affil, LaTeX tells me that it's already been defined elsewhere, but if I use \affil without the package{authblk} then LaTeX simply does not recognize the command \affil and calls it an undefined control sequence. Any ideas as to what may be causing it?

Revtex defines a similar command, the responing counter clashes with package authblk.

Code: Select all

%\documentclass{revtex4-1}
\documentclass{article}
\usepackage{authblk}
\usepackage{blindtext}
\begin{document}
\author{Akcays}
\affil{\LaTeX-community.org}%JB: authblk
%\affiliation{\LaTeX-community.org}%JB: revtex
\author{Johannes B}
\affil{\TeX Welt}%JB: authblk
%\affiliation{\TeX Welt}%JB: revtex
\title{MWE}
\maketitle
\blinddocument
\end{document}

BTW: please always prepare a minimal working example just as i did above. You mentioned revtex in the tags, that was the only hint i had. Having all the information needed is much better than hunt for them. And it makes helping so much easier and faster.
