Hello,

Searching for a \thanks equivalent command on ConTeXt, I ended up on
http://wiki.contextgarden.net/LaTeX_Thanks.

But I didn't like that solution, because the author footnote is placed on a
new area instead the same as text footnotes.

So I made a simple solution, that the author footnotes is placed in the
same area and doesn't interfere on real counter. I want here to share my
solution, below you can see it.

\definestartstop[author]
  [before={\savenumber[footnote]
    \resetnumber[footnote]
    \start
    \let\thanks\footnote
    \setupfootnotes[numberconversion=set 2]},
   after={\stop
    \restorenumber[footnote]}]

It can be used as that:

\startauthor
  Wagner Macedo\thanks{Brazilian citizen}
\stopauthor

Of course, I could did a \author command, but I generally prefer to use
start/stop blocks.

What do you think? This could be improved?
