Engineering is going to make some changes to the site tomorrow to address a couple of the most common concerns that arose out of the last release. You'll see these changes on profile pages.
When you visit your profile page after the change, it will include a Chowhound header, and the board selection navigation (including saved boards), so you can easily jump into the Chowhound boards.
You'll also see that 'My Posts', which is the first page you see when you click on view profile, has been renamed 'My Threads' -- it works the same way as it did before.
Renaming it frees up 'My Posts' for an actual view of the text of your posts, similar to the old All Activity. Unlike All Activity, however, this will be limited to Chowhound posts only -- CHOW comments won't be included. If you're viewing someone else's profile, you'll have this view of their recent posts, as well.
