I think I figured it out... each of us has our own logon id for the site, and Jimmy created an account for kcac.fans, which allowed anyone to post anonymously to the blog by emailing to kcac.group(at)blogger.com. I've deleted that member account, so it won't work any more. If any of you want to be able to email posts to the blog, click on the "Blogger" icon in the upper left corner of the blog, click the Settings tab, click Email, and complete the email to blogger address. Make sure the Publish button is checked. I think this will stop the spam postings. Have a great day!
