We're investigating reports of users not being able to comment on IE8/9 from the embedded form. We hope to have a fix out shortly, but in the meantime we encourage admins to switch to either the full-page or pop-up forms which should be working without issue.I have made the change they recommend.
Thanks for your patience, and we'll make sure to update this post as soon as we have more info.
I want some of this
