From Ashley Cheng’s blog, Bethsoft producer:
This is a subtle change but we’ve rebranded our forums. Instead of just being the official Elder Scrolls forums, its now called the Bethesda Game Studios forums.
Notice that the tags for this post are Oblivion and… Fallout 3.
Edit: Ashley removed the tags now, but it’s too late, we all saw them :)
I think you can connect the dots.
