Does This Mean I'm Official Now?

I was informed by my editor that I now have a publicist assigned to me. What does a publicist do exactly? Heck if I know--yet. Hopefully, I will soon. And when I find out, I'll let all of you know. : ) But it is exciting all the same to know I now have someone who can help me know what I should do as a new author to get my book out there to the masses. Book launches and book signings here I come! Only two more months until Forbidden Sea is out in stores. I must admit there were times I never thought this day would come.
