I outsmarted Big Brother! I made the comment form a full page (FYI, settings > comments > Comment Form Placement > full page) and now you should be able to comment! Even if you work here at Widget Co!! AB and Alissa, if you'd do the same, you would be able to once again receive my amazing words of wisdom!! :)
Sigh. Unfortunately, my brilliance took time and experimentation, and I tried different templates to see if that would fix it. Now it looks weird. Grrr.'
