I am testing software on this site which may cause an inconvenience for users who wish to post comments while using Internet Explorer. Users of other browsers (Mozilla, Firefox, etc) will not experience this issue.
If you are using Internet Explorer and wish to post a comment, you will see a window pop up that says undefined. If you click "OK", you'll see another window with some other text and will be able to enter your comment after clicking "OKAY" in that window. If you click "CANCEL" in the very first window that pops up, you'll be able to enter your comment.
I know this is a bother, but the developers are working on that bug right now and hopefully it will be fixed soon. Please let me know of any questions.
