We’ve had a lot of complaints over the last few months about problems with registering to comment on the site. There were two problems. First, the banner was over the top of some of the entry boxes on the form. Second, the confirmation emails sometimes didn’t show up (because a bunch of ISPs had blocked the domain of our hosting service, it turns out). Both problems should be fixed now, so if you haven’t registered to comment, could you give it a try and let me know if it works? Hopefully, everything should run smoothly.
