If you'd prefer to start on the Group dashboard when you log in, instead of the Services page for your own account, you can set that at the very end of the dashboard page. There, you'll see the text: "You are using the (services or dashboard) page as your home page." If you'd like to switch to use the other one, just click the link that follows.
From then on, you will be taken to the selected page when you log in. If you'd like to return to that page at any time, from any other page on the site, just click the Pobox logo in the top left corner to return to your chosen home page.
