JFBConnect on Register page

Hi,
I was able to get the JFBconnect login button to show up on the login page. goodtalktnt.com/component/community/profile?Itemid=121
but it does not show up when you hit the signup or register button.

Hey Alex,
Would appreciate your help on getting the FB login button to show up on the register page. I think the problem I'm having is because I don't use JomSocial to register but i don't know what the file is to make the changes to add the button to this page:
goodtalktnt.com/component/community/register?Itemid=121
This is the page that you go to when you hit the 'signup' button on the top right of my site.
I tried adding the code to the frontpage.guests.php file but it doesn't work. I'm guessing it's another file but I don't know how to affect it on that page. Maybe there is a way to find the file name and path to it. Can you help?

Thanks for your time.

Alex,
This was already done. the code is placed in the register.index.php file and placed in my overrides folder. See screencast.com/t/1eq23pIrvxv
It's also in the overrides folder. See screencast.com/t/19HlkxtRxagN

Only thing I see that could be a problem is that the JS Template selected is called blueface screencast.com/t/Z1x6qQO4R
but there is no register.index.php file for this template.

It's working in the original location but not when I place the file in the overrides.

Think I realize why. It's not in the right place in the overrides.

Nope. No such luck. It does not work if I place it in
templates/tx_mainstream/html/com_community/templates/default/register.index.php

but it does work if I place it in
/components/com_community/templates/default/register.index.php

Any idea why?

It did work. Thanks for your patience.
Think I may have mis-understood how to create the JS overrides folder. I basically copied the entire com_community folder and put it in tx_mainstream/html

I guess the only files I should put in there are the ones that I make customisations to. Correct?
