A crosspost of up to 20 newsgroups was tested. While this may not be a valid email address, it is at least an attempt. A post with a much more massive signature was not posted, but this appears to be more a matter of article size than signature size, as no error message was presented to the user. Although appearing empty in client, external views of test article showed three lines. These three phantom lines also served to avoid server's empty article prohibition.
