On the advice of Sean, I’ve changed a few things about the commenting system. When you click to add a comment, you’re now sent to the comments section of the individual archive page, rather than getting a pop-up window.
Also, I’ve added a “Recent Comments” section to the sidebar on the main page, and a Last 100 Comments page (also available in a link below the Recent Comments).
There does seem to be an issue with the browser remembering previous login information, but I’m not sure where it’s occurring. I’m working on that. Anyway, if you have any problems, just let me know. And if you like the new format, let me know that too. Feedback is always appreciated.
