1. Go to the Google Groups main page at http://groups.google.com/. To go to that web address with your web browser, write that address to the address bar of your web browser and press the Enter key (or equivalent key) on your keyboard. 2. If you have followed step 1 and you are now on the Google Groups main page and you see a "Sign out" link at the top of the page and you also see an email address on the same line and if that email address is not the email address you want to sign in to Google Groups, then you need to sign out from Google Groups. 3. If you have followed step 2 and you now see a page where your email address and password are asked, then you need to type your email address to the "Email" text field and your password to the "Password" text field and press the "Sign in" button. Instead of pressing the "Sign in" button, you may also press the Enter key (or equivalent key) on your keyboard. 4. You should now be signed in to Google Groups. If you are not signed in to Google Groups, see question "Why can't I sign in to Google Groups?" below for instructions.
