When Twitter module is installed the 'login button' automatically shows in register slide. I would love to design my own Twiitter Login Button and put it in header.tpl. When I put my designed button it also shows in 'Login Menu'. I am thinking of having different twitter buttons for 'Register Slide' and Login Slide'. So In twitter module, which file handles this automatic 'Login Button' in register slide? I tried locating the files but I am out of luck. Thanks.
