I notice on my tablet that the small top right corner "join" and "sign in" buttons don't show on my tablet when I hold my tablet vertical. I'm concerned that other users that use tablets won't know where to sign in, as when they hold the tablet vertical the sign in buttons in the top right corner doesn't show.  Currently this join free button redirects to the join page, but I want to change the big "join free" button to the sign in popup that users see when they click on sign in.  

Sorry I hope i make sense my English is not so good.

I would appreciate help in this regard.

Thanks in advance.

Thanks
