I'm using your plugin (as the matter of fact, two of them... FB and TWITTER) and i'm so pleased with it, but there's a cuestion...
Is there some way to know identify with social network did the user use to login? I mean i can use:
<?php wp_get_current_user(); echo $current_user->ID; ?>
To know what's the wordpress user's ID, but how can I get then the Facebook ID to use graph to get the picture in this way.
And gravatar or twitter avatar if is using something else.
Thanks for the answer.
