This plugin has worked great for me. Integrates well into Theme My Login, but needed to code some CSS to make it look great. Tested both Facebook and Twitter logins, and they work great, but logging in with Google+ does not at this time. Google is removing OpenID support and this plugin needs to be updated to support the new authentication method. Apparently it's being worked on, but until then you'll have to do without Google+ login with this plugin. Just a heads up for that. Otherwise, this is a great plugin.
It's a good plugin however can become a great one with the addition of support for shortcodes.
easy to tweak in order to do more with it !
