This is another place to advertise your business. The entry forms work well and offer plenty of options to specify business categories, description, hours, etc. To its credit, this site allows you to hide your exact street address - handy for a home-based mobile service with no storefront when the home is not in a business zone. However, good luck trying to update your information if you move or get a new phone number. I tried updating in 2010, it never changed, and I just tried again. I'm not sure, but I think the story is that it's delayed for security purposes. In any case, you will get noticed more easily by contributing in other venues. This one is strong on promises and weak on delivery. The site is safe to visit. If you sign up, expect a call to sell you more services. If you say no, they will stop calling.
