"Just recently became pagan"? Well as others have said, Pagan is a term, not a path. Personally I don't care what you call yourself as long as you have a set of beliefs, morals, and rules you agree with. Regarding telling people, do you have a reason to? I mean, if you're serious, your parents/guardians need to know if you're under a certain age, but otherwise its nobodys business.
I wouldn't tell anyone including your parents, just yet. You might wish to tell them you are doing some soul searching but haven't decided on anything yet. I say this because it appears you discovered an article saying how there are Pagans walking among us and you decided to join without much else. Not to offend, just my view. It's fine if you are that new, everyone has been their, but I would study a bit more before making a lifelong commitment. Make a list of beliefs and a list of reasons why you wish to be pagan. Example 'I want to cast spells and fly' next step should be to study and research to discover if your views are Pagan or not. [Helpful tip, magick cannot make you fly, its fantasy not reality] as with your beliefs, try to find a path that preaches similar views. Or, try researching religious paths associated with a culture you feel interested in like Celtic or Norse.
Pagan is a rather large umbrella you could get lost in, so try to research, and understand what you believe and don't believe. These beliefs will change as you grow, but you can use them as a starting point.
