I have heard that some of you have never been able to post comments since we put in the registration system, and others have had trouble lately. Please try again if you so desire; we’ve found and eliminated a few small and subtle bugs in the system, and I hope that will finally take care of these problems. I know, I’ve said that before — so please email me at firstname.lastname@example.org if you still can’t post. And thank you for your patience.
UPDATE: Many of you have problems with your connection timing out, so that you have to sign in again. Unfortunately, that time limit is set by TypeKey and there’s no way to alter it.
