Section and subsection numbering

[Ista Zahn]

Hi, sorry if this is obvious, I couldn't find it in the FAQ. I'm using
the article class, and I want section and subsection numbering like

I
1
2
II
1
2

instead of the default

1
1.1
1.2
2
2.1
2.2

I've changed the section numbering to Roman, but I can't figure out how
to suppress the section numbers in the subsections. I'd appreciate it if
someone can give me a pointer.

Thanks,
Ista

\renewcommand\thesubsection{\arabic{subsection}}

(This will affect the output of \ref too).

Additionally, you may want to
\renewcommand\thesection{\Roman{section}}%
