I have learned a few things that may help anyone out there who would like to comment, but can’t:
1. You may not be able to register with TypeKey unless your registration name is all one word: johnsmith or John_Smith, but not John Smith.
2. Make sure you have cookies enabled.
3. If you have a firewall, you may have to take it down in order to comment.
Although traffic is up, comments are still down since I put in the registration system. I hope these points help, and will let you know others as I discover them. That may be awhile, however, as I am something of a luddite when it comes to these matters.
And again: comments are largely unmoderated, although I do look in from time to time. Genocidal and abusive comments are not welcome, and will be removed if I see them. If you would like to talk to me, comments are not the best way; I can be reached at firstname.lastname@example.org. If you get no reply or a late one, however, please pardon me: I get hundreds of emails daily and have quite a lot to do besides.
