I'm interested in integrating a separate site with my current. The reason why is because they're a Forum Site and we're a Blog that's interested in having a Forum.
I was thinking about just creating a button on our Navi Bar that would lead to the other website but we want the accounts to be linked. So when you create an account on Site #1, it carries over to Site #2.
Site #1 : www.Spawnshield.com
Site #2 : www.thegamersrepublic.com
Site #1 is a Wordpress Site
