Social Network Login, search and Register

Hello,
first of all congrats for this plugin.

I have a few issues here.

1 – I’m trying to use the plugin, and when i activate the connect with social networks it doesn’t show anywhere.
2 – How can i activate the search bar?
3 – How does work the registration? I try a few times, but no email arrives, the login doesn’t work, can you help me here?

Thanks in advanced.
