Here's my python code for filtering google groups again. You need to bookmark
pyc files to run them from the bookmarks in firefox. You also need to create
the bannedAuthors.txt and bannedSubjects.txt files.
# remove banned author and authors with mostly caps
# to compile to pyc
#>>>import py_compile
#>>>py_compile.compile("file.py")
