UPDATE: Here is a workaround to the TypeKey problem that auditioning CBB contributor Krisin told me about. It works for me.
If you have followed our previous instructions and still can’t post comments, after signing in to TypeKey, look at the address bar on your browser, and see if the web address says http://www.celebrity-babies.com/whatever_the_topic_is?commenter=your_username (where your_user name is YOUR username on TypeKey). If it says that (as it should if you successfully signed in), erase the part where it says ?commenter=your_username and hit enter. The page will reload and you should see the area to type your comment. You may need to do this each time you want to comment.
Let us know if this works for you! (If not, unfortunately, we don’t know what else to tell you to do!)
