I’ve also searched for a way to get from the forum back to the main site, and agree that a direct link somewhere on the page would be great.
As the pixls.us site is divided into Articles, Blog, and Discuss, an easy way to get to all three places from all three places would be nice, preferably at the top, but at the bottom would be much better than nowhere at all.
I’ve been on other sites where the forum was “isolated” from the main site, and it’s always frustrating to not have a link to get to the main site.
