title: Checking whether a user is logged into Flattr?
body: <p>Is there a way to test whether a user is logged into Flattr?</p>
  
  <p>The idea is to set up a "I'm-ready-to-donate-wall" that only Flattr users are allowed to pass. However, unlike a paywall, the user is <em>not</em> forced to click a flattr button; I just want to make sure that he's ready to flattr anything if he/she likes what he/she sees. I am not interested in his/her account credentials either.</p>
  
  <p>Obviously, this is a thinly veiled scheme to get users to sign up to Flattr. I don't know whether this is a good or bad idea, but it might be worth a shot.</p>
