Several of the family have asked how to log in to post comments. My reply basically has been: just post them. That is to say, comments can be posted without logging in.
Selena discovered a few days ago that indeed the site security was set up wrong, and one did have to log in to create a comment on a posting. This has been fixed.
If anyone feels like commenting on any post, simply click the "comments" link at the bottom of the posting you want to comment on. You will no longer be accosted by the login prompt when you hit the "POST" button.
Of course, this is all Selena's fault. If she'd post comments more frequently she would have discovered this much sooner! (-:
