We list the actual URL not the vanity URL because it makes the site easier to track. It's simply one of many editorial standards we use to maintain consistency in the directory.
Please read the submission guidelines and follow them. That will give you the best chance of having you website accepted into the directory without unnecessary delay. If you are having trouble submitting now, you might want to try again in a few days. (Other users have reported problems accessing the public side at present.) If you still are having problems after that, you may want to check the bugs and features forum here to see if there are any problems with the submission process.
