I want everyone to notice that there is a new activity tab on your account page. If you are signed in, click on "My Account" up top to the right and you'll see a list of new activity in any thread or page that you have commented in or that you are watching (you can watch any page, any site category, or the whole site by clicking the appropriate choice at the bottom of each page).
The activities in your activities tab are organized by topic and you can mark them as "Read" so as to only get new activities. This should be a great way to keep up with your GUS behavior. Of course, you can also choose to receive emails about new posts, etc., or both. Emails work fine for our site since our forum and page comments are not too busy. But in the future should we become more busy emails could be difficult since your inbox could be flooded. The activities tab is new and some improvements will likely be made in the future. Here is the link for your account, and of course the link is always up to of the site:
