cd /home
chgrp -R users janice
That will change it recursivly, however there could be other ways.

Core dumps are files for debugging perpouses, and are quite large, normaly
around 300k so if you are getting these a lot (with other ommands as well)
you could possably fill you disk quicker than you think. Memory problems are
one big cause of "core dumps", a way to track down what is causeing them is
to use 'gdb -c core' (of course in the directory where the file "core" is)
that will tell you which program caused the dump, further infomation can be
gained with gdb to analise the data, man gdb for howto do that.
