Cecil, Please contact me directly for more details. Here are some answers to your general questions. Question - How do you go about joining ? Answer - Contact me and I'll send you my general information FAQ and instructions on joining. I want to make sure you understand the details including the fact that the DNA sample must come from a Campbell male. Question - Do you do the dna sample at home and mail it in? Answer - Yes, with a small plastic scraper that collects some skin cells from the inside of you mouth. It's as invasive as brushing your teeth. Question - Do you recommend the 25 marker test? Answer - Yes, the 25 marker test is $169. I recommend this over the 12 marker ($99) or the 37 marker ($229). One can always further upgrade to 37 later. Question - How long does it take to get the  results back? Answer - Because of the National Geographic project it was taking a long time (2-3 months), but this backlog has been cleared out. Now I expect results in 4-6 weeks.
