looking for groups

IIRC, alt.english.usage was a high-volume group until recent years.  It
seems to go by at least a day now with no articles.  Have I got the
group name wrong perhaps?

I'm also looking for a group on economics.  I'd like to ask questions
and learn a bit from people who study it.  We have sci.econ, but it
looks dead on Eternal September.

Thanks!
