The R1b and Subclades Forum hosted at WorldFamilies is very active - with over 23,000 postings in 749 Topics.
There are great discussions - from "How-to", to Deep Clades, to correlating the Haplotree to prehistoric times, to current events and ancient history, to just about anything you might imagine that touches on Haplogroup R1b and its Subclades. Kudos to Rich Stevens, the Moderator.
