This is usually because there is some type of notice on your account waiting for you to take action on it. It could be anything from your email address is bouncing back to us, or notice posted by a moderator, etc. 

All of these are also sent via email as well, so you should have seen it and been able to acknowledge it directly from your email. But if you miss the email, you can just visit your profile (or really any page of the website) and the notice will show up for you to acknowledge.

P.S. Any notices only show if you're logged in with your own account. Guests or other users of the site can not see them.
