I have a different analytics script for my main site and subdomain (forums). According to analytics my main site received 80 hits from my forums and my forums received 250+ hits from my main site. My question is...Do visitors that find me through my main site, leave to the forums, and then return count as a referral from the main site to the forums AND from the forums to the main site? or Does it simply count as a referral from the main site to the forums only?
