Just to let you know. Although you can create your entry without registering this will mean you can't amend it in future. I would advise you to register first before adding your business to the directory. If you've registered AFTER adding your business then let me know along with your login name and I'll sort it out.
You can also add your logos to your directory entry. LOGO is for the picture that is displayed after customers click on your entry, whilst ICON is what they see when searching through the listings.
