Yes! I would love to join the Poland project. I'm not sure how much I can contribute, but I'm willing to learn and would love the opportunity to help.
My g-grandparents came from Poland, changed their surname when they came off the boat and left bread crumbs as to their Polish Roots. My g-grandmother told her children (my grandmother and her brothers) the family surname on her deathbed, but unfortunately, the kids only knew how to speak Polish, not spell it so we only have the pronunciation.
My mom has done her MtDNA, but I do not have enough knowledge of the family to tell if I'm getting any matches.
