I want to encourage people to sign in with facebook/google/twitter rather than the relatively more complex creating an account and then maybe forgetting their login details.
Currently the "alternative logins" are to the right and not put in the spot light. Is there an easy way for me to switch them over the the left? @trevor has a very cool layout on his theme emphasizing social logins. (but until i become comfortable with the side menu of majestic, i'll have to jerry-rig lavender)
You can change login.tpl to http://pastebin.com/GpRje1Ug that should put the social logins to the left.
