Regarding this issue.
Step 1, Please select Front page template for Threads Index page
Step 2, Go to Settings => Reading => Front page display => Threads index
We would like to be able to do something like your header for this site. I can see it is from another theme but the forum itself is on a different sub-domain.
How could we achieve this but instead of having the forum on a sub-domain, we just want to have it as one of the links and other links will work with second theme (ie. One Engine or something).
