I've turned off TypePad authentication for comments, so no more log-in problems. To compensate, I've cranked up the junk filters, so, for example, if you post more than two hyperlinks in a comment, you might not make it through the filters. Also, I'm requiring an e-mail address, but it won't be published and you can pretty much use any e-mail address in there. And finally, if you're a regular commenter and you spot some junk or any trolls, please let me know.
Enjoy your hassle-free commenting!
