Call the Realtor on the sign? Realtor vs. Real Estate agent? interviewing for a Realtor... What?!?!

in this video, I answer three questions in the real estate realm that you didn't know you had! do I have to call the number on the for sale sign? is my real estate agent a realtor? how do I actually pick a realtor? I personally did not know the answer to these questions before I entered the realm of real estate. I'm hoping that by sharing this knowledge, other people won't be as baffled by these questions when they come about. help me spread the word and share this video so people know what the right answers to these questions are
