WARNING TO LIST ADMINISTRATORS: Do not enable arch ives for an open list, or you will wind up with spam in the archives which is extremely difficult to remove (requires hand-editing of the archive text files, then a complete rebuild of the database). If you use archiving, you must limit posts to members-only or require approval of postings by the administrator.
