Online business Question.?

Today I bought a domain name, and already signed up with a web hosting site. My online business is a non-profit business. I DON'T accept any forms of currency. I simply give free advise. Do I need a business license for this. Again no profit is made by my company, at all. I built this business so I can help people make the right buying choice. (Please no negative comments). I need a serious answer. Thanks
