You're fine! The queue is very long right now, which always happens whenever there's a surge in registration like this, and it will almost certainly take a while -- depending on where in the queue you are, it may take a few days. You can keep using your journals normally (posting, commenting, etc) and then eventually you will get a message in your inbox saying that your entries are there and it will be like magic! and then a little while later you will get a message saying that your comments are there and it will be like magic! :)

EDIT: hee hee hee, you can tell that I answer my comments in the order they hit my inbox without reading ahead. SORRY FOR THE DOUBLE ANSWER
