[Plugin: Social Connect] Social login without commenting?

I really like this plugin – but I have a feature request. I’m using Nextgen gallery voting plugin, and I’d like to be able to log users in with Social so they can vote on photos, without telling them to

a – go down to the comment section to login, then

b – refresh the page to see that they are allowed to vote now.

Without this functionality, I have to get them to sign up for my blog in order to vote, or leave my vote system at the mercy of bots.

I tried cutting and pasting the “sign in with facebook” link from Social’s own button, and putting a text link to that code in the post, above the gallery. But clicking this link doesn’t actually even log the user in.

This might not be Social’s problem.. but of course I’d like to get people logging in with Social to get them engaged in commenting, participating etc on the site. and a login button wherever I want it would be good for that.

Here’s the kind of page I’m talking about.
