Fine with me. I don't mind basic sharing with anyone. Look for me as Muanetu (Sonia L W) on 23andMe. Have you all uploaded to GedMatch as well?
The thing with mtDNA is that it doesn't mutate rapidly. I took the full mtDNA test at FTDNA, have 2 "mitocousins," matching on the full loop. They also took autosomal tests at 23andMe, but based on those results our MRCA is beyond 5 generations.
