Oddest part is that Steph doesn't seem to realize the url names https://community.secondlife.com http://wiki.secondlife.com
See the part that says "secondlife.com" ... that's the domain name for them both, meaning its the same domain. See the part that says "community" and the other that says "wiki". Those are the subdomains of "secondlife.com" .... in other words, both of those subdomains are part of the same domain. So I second what Qie said, what is Linden Lab gonna do, sue themselves?
