package submission and binary versions

From reading the CRAN web page, it appears that you should not submit

precompiled binary versions of your package, but rather that these
are built for you by someone working with CRAN.  I submitted my
package using R CMD build but without the binary flag on.  I'd like
to have a binary version available for Windows users. Should I submit
a precompiled binary version as well?

No, as it said.  If your package passes its tests on those platforms, 
binary versions for Windows and MacOS X appear automatically (thanks to 
Uwe Ligges and Stefano Iacus).  They even get updated for new R versions 
(and R 2.1.0 is imminent) when otherwise new submissions would be needed.

(You could have asked CRAN at r-project.org about CRAN questions rather than 
the world.)
