Nice plugin and I appreciate Linkedin implementation .
I was able to implement the plugin on Multi-Site installation . I had to activate it Multi-site wide .
I wanted to display ' sign-in option ' on every page, so I have used wp_head hook and managed to display on it available on header
But, there is a problem with < li > tags which were used in ' bc_oauth_templatetags ' file. A logged in user could see empty lines and it's kind of embarrassing . This is not happening in all themes, but some themes like twentyten .There is a serious problem with twentyelven and it is completely broken when I tried to use Bc_oauth option on header .
Could any one help me to get rid of < li > tags ?
