How to get a ফেসবুক cap?

I tried connecting my ফেসবুক account to this site to get this cap. That didn't work. Do I need to যোগদান a ফেসবুক club on this site, if আপনি have one, to get this cap? অথবা is it enough just to add my ফেসবুক account as in ফেসবুক লিঙ্ক to my profile? Would that do the trick? How did আপনি get your ফেসবুক টুপি on this site? Am I too late for this cap, অথবা what? Everyone else has one.
